From: Kai Kang <[email protected]>

diffstat checks variable CC. If options '-I', '-U' or '-D' is included in CC, variable CC will be wrongly filtered and only such as 'mips64-wrsmllibn32-linux-gnun32-gcc' left. It shows warning message during configure:

| checking $CC variable...broken
| configure: WARNING: your environment misuses the CC variable to hold CFLAGS/CPPFLAGS options

Disable such check for OE.

+m4 function CF_CC_ENV_FLAGS checks whether variable CC contains options '-I', '-U'
+and '-D'. It is not suitable for oe that option such as '-D_FORTIFY_SOURCE=2' may
+be included in CC. And then CC will be wrongly filtered.
+
+So comment out CF_CC_ENV_FLAGS from function CF_PROG_CC.
