[Buildroot] [git commit] package/heirloom-mailx: fix link issue with getopt

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=d4171c5192e44f2733ccd217222680e597e6397d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

With NIOS2 toolchain, heirloom-mailx fail to build
due to missing -fPIC when linking with its own getopt.

Since static build for heirloom-mailx is disabled,
always pass -fPIC in CFLAGS.
