alsa-lib: Lift the limitation to use gcc only cross compiler

alsa-lib configure tries to see that if CC variabled doesnt contain
'gcc' then it tries to guess and redefine CC to be something gcc, which
doesnt work with OE since we define CC to have sysroot and options
attached to it. So all tests fail when configure constructs the CC for
cross compiler like this. This portion is not needed at all

+Subject: [PATCH] build: Do not try to detect cross-compiler
+
+cross compilers are passed via path may not be a gcc based cross
+compiler in such cases this check fails and try's to force gcc based
+cross compiler detection, This code is a convenience that limits the
+build system
