Description changed by jdemeyer:
Old 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.
>
> '''Apply''' to the SAGE_ROOT repository:

New description:
1. Added a test for a C99 compiler, since some packages require that.
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 script portable, so it doesn't require bash (instead of
#12621, which proposed to force `bash`).
'''Apply''' to the SAGE_ROOT repository:
1. [attachment:12112_from_12576.patch] ('''positive_review''', see
#12576)
2. [attachment:12112_update_prereq.patch]
'''Download'''
[http://boxen.math.washington.edu/home/jdemeyer/spkg/prereq-1.0.tar.gz] to
`SAGE_ROOT/spkg/base` and '''delete''' `prereq-0.9.tar.gz` (reviewers:
look at [attachment:prereq-1.0.diff] for the changes)
