Bug#980957: llvm-toolchain-11 autopkgtest segfaults on armhf

[Gianfranco Costamagna]

control: forwarded -1 https://sourceware.org/bugzilla/show_bug.cgi?id=27659
control: affects -1 src:binutils

Invoking the clang with -V shows a failure in ld.bdf linker, a failure that doesn't happen with gold linker and with object files (crt*.o) copied on local directory.

I opened a bug against binutils people to track it down, hopefully they can sort what is segfaulting there.

thanks

Gianfranco
