knxd: fix build on macos

Browse source 
knxd compilation fails on macos due to clang does not support
exit() builtin function that is used to detect build cc

This commit adds a patch to fix this issue (replaces `exit 0` by
`return 0` in conftest.c)

Subject: [PATCH] Add clang suport as build cc
ccforbuild.m4 comes from gmp project (very old version).
Current version does not support clang due to using GCC exit()
builtin function. clang does not have exit() builtin function.
GMP project fixed this issue by the commit https://gmplib.org/repo/gmp/rev/beda46a3c10d
This patch backports "upstream" change (`exit(0)` relaced by
`return 0` in conftest.c)
