Extended Description

I've received a bug report from our AArch64 team that clang fails on big-endian userspace. Apparently, it has been already fixed in trunk and since the fix is quite obvious, I'd like to request backporting it to 7.0.1.

The commit is r341312, i.e.:

[Aarch64] Fix linker emulation for Aarch64 big endian

This patch fixes target linker emulation for aarch64 big endian.
aarch64_be_linux is not recognized by gnu ld. The equivalent emulation
mode supported by gnu ld is aarch64linuxb.
