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. config/ * lib-ld.m4 (AC_LIB_PROG_LD_GNU): Require AC_PROG_EGREP and invoke $EGREP. (AC_LIB_PROG_LD): Likewise. binutils/ * configure: Regenerate. * embedspu.sh: Replace egrep with grep. gold/ * testsuite/Makefile.am (flagstest_compress_debug_sections.check): Replace egrep with grep. * testsuite/Makefile.in: Regenerate. * testsuite/bnd_ifunc_1.sh: Replace egrep with $EGREP. * testsuite/bnd_ifunc_2.sh: Likewise. * testsuite/bnd_plt_1.sh: Likewise. * testsuite/discard_locals_test.sh: Likewise. * testsuite/gnu_property_test.sh: Likewise. * testsuite/no_version_test.sh: Likewise. * testsuite/pr18689.sh: Likewise. * testsuite/pr26936.sh: Likewise. * testsuite/retain.sh: Likewise. * testsuite/split_i386.sh: Likewise. * testsuite/split_s390.sh: Likewise. * testsuite/split_x32.sh: Likewise. * testsuite/split_x86_64.sh: Likewise. * testsuite/ver_test_pr16504.sh: Likewise. intl/ * configure: Regenerate. ld/ * testsuite/ld-elfvers/vers.exp (test_ar): Replace egrep with grep.
