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.
