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.

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.
