+Date: Mon, 19 Oct 2020 19:05:01 +0100
+Subject: [PATCH] gcc.specs: drop --fatal-warnings from linker options (ia64
+ compatibility)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+```
+$ 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` option from gcc.spec entirely.
+
+Rejected upstream in https://github.com/rhboot/efivar/pull/164.
