[packages] lang/perl: Fixed finding libm and friends due to Ubuntu 11.04 and Debian 6 (Wheezy) using arch dirs for system libraries instead of /usr/lib and /lib.  Patch by Andy Doughertry, submitted by Jan.  Thanks\!

++# Ubuntu 11.04 (and later, presumably) doesn't keep most libraries
++# (such as -lm) in /lib or /usr/lib.  So we have to ask gcc to tell us
++# where to look.  We don't want gcc's own libraries, however, so we
++# filter those out.
++# This could be conditional on Unbuntu, but other distributions may
++# follow suit, and this scheme seems to work even on rather old gcc's.
++# This unconditionally uses gcc because even if the user is using another
++# compiler, we still need to find the math library and friends, and I don't
++# know how other compilers will cope with that situation.
++# Still, as an escape hatch, allow Configure command line overrides to
++# plibpth to bypass this check.
