Found while trying to compile Serenity, more precisely while building the binutils part of the toolchain (i686 GNU):

This appears to be caused by the following command from the binutils-2.38/intl/configure script:

if $LD -v 2>&1 </dev/null | egrep '(GNU|with BFD)' 1>&5; then
  [...]

The issue has seemingly vanished after implementing egrep. My attempts to minimize the "test case" have failed.
