[PATCH] macos: move NO_REGEX in macOS to config.mak.uname

[PATCH] macos: move NO_REGEX in macOS to config.mak.uname

[Carlo Marcelo Arenas Belón]

29de20504e (Makefile: fix default regex settings on Darwin, 2013-05-11)
added this flag to the Makefile since Mac OS X 10.8 at the time didn't
have a working REG_EXTENDED|REG_NEWLINE

move it to config.mak.uname where all the other system specific settings
are kept since e1b6dbb554 (Makefile: hoist uname autodetection to
config.mak.uname, 2013-01-03) and update the rule so it only applies to
those known broken versions as the problem was most likely fixed in the
next version when Apple imported TRE on their libc.
