gmp-6.2.1 on arm64 with lto stuck in infinite loop

[Jannik Glückert]

When using gmp-6.2.1 with link time optimization on arm64, gfortran
(specifically f951) gets stuck in an infinite loop on argument parsing.
This is on Gentoo Linux.

After some digging around I found the regression to be in
18082:c5d0fcb06969
changing the name of binvert_limp_table back to __gmp_binvert_limp_table in
mpn/arm64/bdiv_q_1.asm fixes this.

Note that I'm absolutely clueless about asm, I discovered this after
messing around a bunch.

Steps to reproduce:
Build gmp-6.2.1 with gcc, ld.bfd and lto ( -fuse-linker-plugin -flto )
Invoke gfortran's f951 with valid arguments - in my case it occurred during
the configure checks when building gcc

Additional information:
gcc 10.2.0, binutils 2.35.1
uname -a: Linux jbookpro 5.9.11-arm64 #1 SMP Thu Nov 26 09:48:59 CET 2020
aarch64 GNU/Linux
config.guess: aarch64-unknown-linux-gnu

Attached is the output from configure

Best Regards
Jannik
