I don't quite understand why that wouldn't work.

The way Horiguchi-san did it has been supported by autoconf for
a good long time now, so I don't think command line syntax is
the issue.  Could that CFLAGS setting be interfering with some
feature test in our configure script?

Commits

  1. Use CFLAGS_SL while probing linkability of libperl.

  2. Select CFLAGS_SL at configure time, not in platform-specific Makefiles.
