sys-libs/efivar: drop -Werror equivalent for linker
ia64's ld does not implement '-z relro'. This means 'z relro --fatal-warnings' always fails on ia64. The change drops '--fatal-warnings'. Reported-by: Émeric Maschino Closes: https://bugs.gentoo.org/749963 Package-Manager: Portage-3.0.8, Repoman-3.0.2 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

+Subject: [PATCH] gcc.specs: drop --fatal-warnings from linker options (ia64
+ compatibility)
+
+```
+$ LANG=C make HOSTCC=x86_64-pc-linux-gnu-gcc CC=ia64-unknown-linux-gnu-gcc HOST_ARCH=ia64
+ia64-unknown-linux-gnu-gcc ... \
+ -o libefivar.so ...
+/usr/libexec/gcc/ia64-unknown-linux-gnu/ld: warning: -z relro ignored
+collect2: error: ld returned 1 exit status
+make[1]: *** [/home/slyfox/dev/git/efivar/src/include/rules.mk:32: libefivar.so] Error 1
+```
+
+ia64 (and a few others) binutils target does not support '-z relro' and always
+issues a warning. --fatal-warnings spec option turns the build into always failing one.
+
+The change drops `--fatal-warnings` options from gcc.spec entirely.
