Subject: libelf: fix build with clang16+ (#38915)

libelf fails to build with clang16+ due to Wimplicit-int and
Wimplicit-function-declarations becoming errors by default. This breaks
the configuration stage, so no build takes place. This patch fixes this
by passing -Wno-error=implicit-int and
-Wno-error=implicit-function-declarations as cflags.
