[PATCH] kbuild: dummy-tools: pretend we understand __LONG_DOUBLE_128__

From: Jiri Slaby
Date: Wed Aug 10 2022 - 05:26:34 EST


There is a test in powerpc's Kconfig which checks __LONG_DOUBLE_128__
and sets CONFIG_PPC_LONG_DOUBLE_128 if it is understood by the compiler.

We currently don't handle it, so this results in PPC_LONG_DOUBLE_128 not
being in super-config generated by dummy-tools. So take this into
account in the gcc script and preprocess __LONG_DOUBLE_128__ as "1".
