- 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.
