Subject: [PATCH] Gentoo: add --with-extra-soversion-suffix= option

--with-extra-soversion-suffix= will allow Gentoo to
distinct libbfd.so and libopcodes.so to have more precise
SONAME.

Today --enable-targets=all and --enable-64-bit-bfd change
libbfd.so ABI:
--enable-targets=all adds new symbols to the library
--enable-64-bit-bfd modifies BFD_ARCH_SIZE default and
changes sizes of integer parameters and fields to most
APIs.

--with-extra-soversion-suffix= will allow Gentoo to inject
additional keys into SONAME to indicate ABI change and avoid
hard to diagnose crashes when user reinstalls libbfd.so
built with different flags (see https://bugs.gentoo.org/663690).
