PREFIX and INSTALL_BASE are mutually exclusive. If both are supplied
by INSTALL_BASE being set in PERL_MM_OPT ExtUtils::MakeMaker will
produce an error:
$ echo $PERL_MM_OPT
INSTALL_BASE=/home/avar/perl5
$ make -C perl PERL_PATH='/usr/bin/perl' prefix='/home/avar' perl.mak
make: Entering directory `/home/avar/g/git/perl'
/usr/bin/perl Makefile.PL PREFIX='/home/avar'
Only one of PREFIX or INSTALL_BASE can be given. Not both.
make: *** [perl.mak] Error 255
make: Leaving directory `/home/avar/g/git/perl'
Change the perl Makefile to work around this by explicitly unsetting
INSTALL_BASE.
INSTALL_BASE is set in PERL_MM_OPT by e.g. the popular local::lib
package, from its documentation:
eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib 2>/dev/null)
Many other environments might also have set PERL_MM_OPT before
building Git. This change enables us to build in these environments.
