The libtool.m4 change supplies values for netbsd similar to what's already done for selected other targets.  The patch to libstdc++-v3/acinclude.m4 lets configure rely on the ld version number to determine support for --gc-sections if a cross-build is being done, rather than doing a double-check.

Please always diff vs current mainline first, don't diff vs releases.
Also, libstdc++ patches also go to the libstdc++ mailing list.

Paolo and Ralf, could you have a look? Thanks in advance.

Paolo.
