[Bug libstdc++/35197] New: Native linker can't locate file for -lstdc++ with --enable-version-specific-runtime-libs

[skunk at iskunk dot org]

I have a build of GCC 4.2.3 compiled with
--enable-version-specific-runtime-libs. It fails to link a trivial C++ program,
because the (non-GNU) linker does not know about libstdc++, and the GCC
frontend is not passing an appropriate -L... flag to the linker so that it can
find the library.

$ g++ -o hello hello.cxx
/usr/bin/ld:
Can't locate file for: -lstdc++
collect2: ld returned 1 exit status

$ g++ -v -o hello hello.cxx

-lstdc++ -lm -lgcc -lc -lgcc
/usr/bin/ld:
Can't locate file for: -lstdc++
collect2: ld returned 1 exit status

(I notice that libstdc++ is present immediately under
/opt/tg/lib/gcc/alphaev56-dec-osf4.0g/, which the -L... flags narrowly miss.)
