[PATCH] Fix libstdc++ build (PR bootstrap/51985)

[Jakub Jelinek]

Hi!

Apparently $(inst_sources) is included in libc__98convenience_la_SOURCES and
libc__98_la_SOURCES twice, once directly, once through $(host_sources_extra)
included in $(sources).  On x86_64-linux and others it causes just lots
of bloat (libstdc++.a is much bigger, as several objects are there twice,
and libstdc++.so.6 contains bigger .debug_* sections), but reportedly on
other targets it results in build failures.

Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok for
trunk?

I've verified abilists before Benjamin's change, after that without this
patch and with this patch and the changes are ok (the only changes are some
GLOBAL -> UNIQUE changes caused by Benjamin's patch, with this patch no
abilist changes at all).
