RISC-V: Re-enable -msave-restore for shared libraries.
This re-enables -msave-restore for shared libraries, and uses the
t-slibgcc-libgcc file to get the save-restore routines included directly
in shared libraries so that we don't need to indirect through the PLT
to reach them, which doesn't work.
gcc/
* config/riscv/riscv.c (riscv_option_override): Revert 2019-08-30
change.
libgcc/
* config.host (riscv*-*-linux*): Add t-slibgcc-libgcc to tmake_file.
(riscv*-*-freebsd*): Likewise.
git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@275478 138bc75d-0d04-0410-961f-82ee72b054a4
