> 1. Missing libgcc-unwind.map file
1. Is caused by LINK_LIBGCC_MAPFILE_SPEC being set in gcc/config/sol2.h even if
configured with --disable-shared. This has been around since PR target/59788.
I've had success on solaris 10, both sparc and x86 with following fix.

Also "--disable-shared --with-pic" is still broken (since 4.7.?), see PR
libstdc++/58638 for suggested patch.

Are you sure you want /usr/ccs/bin/as on solaris x86?
Have you tried with gnu as?
--with-gnu-as
--with-as=/usr/sfw/bin/gas
