I'm not sure what you mean when you ask which C library version I am using. Are you asking the version of my libc?
I am cross-compiling on Debian 10 using Go 1.19 and gcc 4.7.4 (but my understanding is that a C compiler is only used for the cgo parts of the Go source tree, and that most of the Go source tree is compiled by Go). My target is Solaris 11.
