[Bug libstdc++/42377] New: libstdc++.dll.a misses a definition of std::string::reserve

["rainer at emrich-ebersheim dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Even though libstdc++-6.dll has: 000000006fc94700 T
std::string::reserve(unsigned long long),
libstdc++.dll.a misses a definition of std::string::reserve!

Which makes it impossible to build libgmpxx against a shared version of
libstdc++-6, see:

beyond that libstdc++.la on *-*-mingw32 has strange dependency_libs definition.
For x86_64-w64-mingw32:
# Libraries that this one depends upon.
dependency_libs='

Which contains build locations!

On my linux system dependency_libs is empty:
# Libraries that this one depends upon.
dependency_libs=''
what I think is right.

this is for trunk rev. 155209
