New description:
1. Since Sage does not need m4, we should not check for it.
2. Remove the useless checks for bison and flex (in the past, we did the
checks but didn't fail if these programs weren't found).
3. We don't need to check gcc/g++/gfortran versions if we're building GCC.
Use the environment variable `SAGE_BUILD_TOOLCHAIN` (introduced in #12369)
for this.
4. Make the portable, so it doesn't require bash (instead of #12621, which
proposed to force `bash`).
5. Added a test for a C99 compiler, since some packages require that.

Comment:
I wouldn't say #12785 is a dependency, it's more like a follow-up.
