Subject: [PATCH AUTOSEL 5.11 32/61] kbuild: dummy-tools: fix inverted tests for gcc

From: Jiri Slaby <jslaby@...e.cz>

[ 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.
