commit: http://git.buildroot.net/buildroot/commit/?id=211916ed46e99c8b5c82ddba62f20371e6a86b01
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When the user has Perl local::lib installed, its environment contains
a PERL_MM_OPT variables which defines
INSTALL_BASE="/some/location". Unfortunately, having this makes the
build of libxml-parser-perl (and probably other Perl related packages)
fail, because it complains that both PREFIX (passed in our .mk file)
and INSTALL_BASE (passed from the PERL_MM_OPT environment variable)
are defined. Since in Buildroot we want our PREFIX to be considered,
we error out when the user has PERL_MM_OPT defined.
