[Buildroot] [PATCH v2 4/4] elfutils: really make -Werror conditional to BUILD_WERROR

[Vicente Olivert Riera]

Apply a patch written by Yann E. Morin to really make -Werror
conditional to BUILD_WERROR. Otherwise it will fail with a message like
this one:

elf_getarsym.c:290:9: error: 'n' may be used uninitialized in this
function [-Werror=maybe-uninitialized]
    arsym[n].as_name = NULL;
	 ^
cc1: all warnings being treated as errors
