[OE-core] [PATCH] make: Fix build on arm/clang

[Khem Raj]

clang defines __arm which is interpreted as non-posix by make build
system but thats not correct when using clang so patch addresses that

+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)
+              ~~~~~~~~~~  ^
