No rule to make target `scripts/extract-cert' when building Linux Kernel - Centos 7, devtoolset-9

I'm trying to debug my build environment for compiling a linux kernel with some patch sets. I installed devtoolset-9 in my CentOS 7 environment to satisfy the minimum gcc version requirement of the 5.15.86 linux kernel branch. When compiling the kernel with a simple

bzImage

, I get the following error: make: *** No rule to make target scripts/extract-cert', needed by certs/x509_certificate_list'. Stop. I then tried to make extract-cert by cd'ing to scripts and running

extract-cert

, but get the following error: cc extract-cert.c -o extract-cert /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: /tmp/ccx32b6d.o: in function `display_openssl_errors': extract-cert.c:(.text+0x3e): undefined reference to `ERR_peek_error' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x7f): undefined reference to `ERR_error_string' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0xc2): undefined reference to `ERR_get_error_line' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: /tmp/ccx32b6d.o: in function `drain_openssl_errors': extract-cert.c:(.text+0xdd): undefined reference to `ERR_peek_error' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0xf6): undefined reference to `ERR_get_error_line' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: /tmp/ccx32b6d.o: in function `write_cert': extract-cert.c:(.text+0x132): undefined reference to `BIO_new_file' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x186): undefined reference to `X509_get_subject_name' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x1a0): undefined reference to `X509_NAME_oneline' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x1b9): undefined reference to `i2d_X509_bio' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: /tmp/ccx32b6d.o: in function `main': extract-cert.c:(.text+0x230): undefined reference to `OPENSSL_add_all_algorithms_noconf' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x235): undefined reference to `ERR_load_crypto_strings' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x23a): undefined reference to `ERR_clear_error' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x338): undefined reference to `ENGINE_load_builtin_engines' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x347): undefined reference to `ENGINE_by_id' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x386): undefined reference to `ENGINE_init' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x3e2): undefined reference to `ENGINE_ctrl_cmd_string' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x437): undefined reference to `ENGINE_ctrl_cmd' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x48a): undefined reference to `BIO_new_file' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x4df): undefined reference to `PEM_read_bio_X509' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x4fb): undefined reference to `ERR_peek_last_error' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x522): undefined reference to `ERR_clear_error' /opt/rh/devtoolset-9/root/usr/libexec/gcc/x86_64-redhat-linux/9/ld: extract-cert.c:(.text+0x57a): undefined reference to `BIO_free' collect2: error: ld returned 1 exit status make: *** [extract-cert] Error 1 I searched in the OpenSSL source code on github and found the symbols that the linker is complaining about. So it seems that it is an OpenSSL error. I have OpenSSL installed, but I'm not sure how it works with devtoolset-9. How do I get the linker within devtoolset-9 to find the OpenSSL library?
