As reported in the PR, libgcc fails to build on Solaris with
--disable-shared: the creation of libgcc-unwind.map depends on
libgcc-std.ver which isn't built in this case.
Fixed as follows, tested by verifying that a --disable-shared
i386-pc-solaris2.10 build gets into stage2 without trying to build map
files, while a default (i.e. --enable-shared) build still correctly
builds the maps.
Installed on mainline; will backport to the 4.9 branch in a few days.
