Subject[PATCH] gcc-plugins: Disable GCC_PLUGIN_CYC_COMPLEXITY for s390
Date
Commit 334ef6ed06fa ("init/Kconfig: make COMPILE_TEST depend on !S390") disabled
COMPILE_TEST for s390. At the same time, "make allmodconfig/allyesconfig" for
s390 is still supported. However, it generates thousands of compiler
messages such as the following, making it highly impractical to run.

Cyclomatic Complexity 1 scripts/mod/devicetable-offsets.c:main
Cyclomatic Complexity 1 scripts/mod/devicetable-offsets.c:_GLOBAL__sub_I_00100_0_main

Since GCC_PLUGIN_CYC_COMPLEXITY is primarily used for testing, disable it
when building s390 images.
