mc: set ac_cv_path_PERL_FOR_BUILD

After mc upgrade to 4.8.29, it introduces PERL_FOR_BUILD [1] and will
result in the below build failure on some system when we build under
a project with long path.
 | make[4]: Entering directory '/buildarea2/WTEST_Regression/Rerun/build_dir/02161802-multilib_pkgs_conflict/qemux86-64-standard-std-OE/build1/tmp-glibc/work/core2-64-wrs-linux/mc/4.8.29-r0/build/doc/hlp/es'

It's beacause the shebang line exceeds 128 which is usually the max
length.

So set ac_cv_path_PERL_FOR_BUILD to fix the above issue and altogether
to remove the build path issue.
