groff: Fix build on Fedora 17

Generally distros keep perl at /usr/bin/perl
But Fedora 17 also has /bin/perl,
this causes groff_1.20.1 build to put perl
interpreter path as /bin/perl
But we set perl location for target as /usr/bin/perl

This mismatch of perl path causes failure of rootfs image creation
like this:

| error: Failed dependencies:
|       bin/perl is needed by groff-1.20.1-r1.ppc603e
