From: Alan Modra <amo...@gmail.com>
Apparently some distros have a nagging egrep that helpfully tells you
egrep is deprecated and to use "grep -E". The nag message causes a ld
testsuite failure. What's more the advice isn't that good. The "-E"
flag may not be available with older versions of grep.
This patch fixes bare invocation of egrep within binutils, replacing
it with the autoconf $EGREP or with grep.
