[OE-core] [PATCH 4/8] mc: set ac_cv_path_PERL to /usr/bin/perl

[Robert Yang]

The shebang's length is usually 128 as defined in /usr/include/linux/binfmts.h:
  #define BINPRM_BUF_SIZE 128

So there would be errors when /path/to/hosttools/perl is longer than 128.

Set ac_cv_path_PERL to /usr/bin/perl to fix the problem.
