Added Files:
	pkgsrc/mk/configure: check-portability.sh

Log Message:
Portability checks, version two.

The actual check has moved into a shell file to allow for nice-looking
code. Instead of only the configure scripts, it scans all files whose
first line matches "#!*/bin/sh". Therefore the check is run no matter if
HAS_CONFIGURE is set or not.

Added a warning (not an error) for every use of $RANDOM that is not
combined with $$, the process ID. $RANDOM is only implemented by bash
and some versions of the ksh.
