Subject: [PATCH] makeinst: Do not undef POSIX on clang/arm

if __arm internal compiler macro is defined then make assumes that the
system is not posix and goes ahead and undefs POSIX, which results in
miscompiling make with clang, since clang does define __arm unlike gcc
which does not, but they both support posix just fine, so here check for
compiler not being clang when __arm is defined before undefining posix

Fixes error like
../make-4.3/src/job.c:507:27: error: too many arguments to function call, expected 0, have 1
  sigsetmask (siggetmask (0) & ~fatal_signal_mask)
              ~~~~~~~~~~  ^
