kbuild: dummy-tools: fix inverted tests for gcc
[ Upstream commit b3d9fc1436808a4ef9927e558b3415e728e710c5 ]
There is a test in Kconfig which takes inverted value of a compiler
check:
* config CC_HAS_INT128
def_bool !$(cc-option,$(m64-flag) -D__SIZEOF_INT128__=0)
This results in CC_HAS_INT128 not being in super-config generated by
dummy-tools. So take this into account in the gcc script.
