Subject: [PATCH] xcompile: Use Walloc-size GCC option

Warn about allocation function calls with insufficient size for the
target type of the pointer.
commit 6ab188ee6c99 ("Makefile.mk: Use Walloc-size GCC option")
introduced this GCC option, then commit d05fe9fd3ce9 ("Revert
"Makefile.mk:Use Localiser GCC option"") reverted it because older GCC
versions did not support it.
This change re-enables it for GCC version equal or greater than 14.1.0.
