[opensuse-project] Why gcc option --enable-linker-build-id is required?

Dear all,

I found enable-linker-build-id option was enabled on gcc48/49. According to gcc manual, the option is disabled by default.[1] Why does suse need the option?

--enable-linker-build-id Tells GCC to pass --build-id option to the linker for all final links (links performed without the -r or --relocatable option), if the linker supports it. If you specify --enable-linker-build-id, but your linker does not support --build-id option, a warning is issued and the --enable-linker-build-id option is ignored. The default is off.[2]
