Hi Steve,
The gnu_ld and gas settings can be removed altogether. They are set earlier
for all linux-targets:
*-*-linux* | frv-*-*linux* | *-*-kfreebsd*-gnu | *-*-knetbsd*-gnu | *-*-gnu* |
*-*-kopensolaris*-gnu)
extra_options="$extra_options gnu-user.opt"
gas=yes
gnu_ld=yes
case ${enable_threads} in
"" | yes | posix) thread_file='posix' ;;
Esac
This patch is OK, with that change.
Thanks,
Catherine
