I did this several years ago for perl 5.6 . As in most cross-compilations,
in the simple cases, you don't have to do anything because the gcc
version of your tool chain should be already to default to the gcc
used by your Makefile. Actually, compiling Perl was even simpler
because the Perl distribution provided 'hint' files to
set compilation defaults. I remember I had to compile in stages to
overcome a difficulty with the blib package and deal with a few
To directly answer you question; first, symlink your gcc to
point to the correct gcc binary. If it does not work, play
with the hint files that come with Perl. If it still does not work,
then learn how to change your gcc flags to use the correct
libraries, includes, and other cross-platform flags.
