kbuild: fix ld-version.sh to not be affected by locale 

ld-version.sh checks the output from $(LD) --version, but it has a
problem on some locales.

For example, in Italian:

  $ LC_MESSAGES=it_IT.UTF-8 ld --version | head -n 1
  ld di GNU (GNU Binutils for Debian) 2.35.2

This makes ld-version.sh fail because it expects "GNU ld" for the
BFD linker case.

Add LC_ALL=C to override the user's locale.

BTW, setting LC_MESSAGES=C (or LANG=C) is not enough because it is
ineffective if LC_ALL is set on the user's environment.
