The wrong logic is using 1 as a suffix instead of -1. So the build script tries to find clang1 file instead of clang.
GEN Makefile HOSTCC scripts/basic/fixdep /bin/sh: line 1: clang1: command not found make[2]: *** [/build/linux/scripts/Makefile.host:95: scripts/basic/fixdep] Error 127 make[1]: *** [/build/linux/Makefile:564: scripts_basic] Error 2 make: *** [Makefile:219: __sub-make] Error 2
Fixes: b8321ed4a40c("Merge tag 'kbuild-v5.18-v2'")
