Fix PR 110066: crash with -pg -static on riscv
The problem -fasynchronous-unwind-tables is on by default for riscv linux We need turn it off for crt*.o because it would make __EH_FRAME_BEGIN__ point to .eh_frame data from crtbeginT.o instead of the user-defined object during static linking. This turns it off. OK? libgcc/ChangeLog: * config.host (riscv*-*-linux*): Add t-crtstuff to tmake_file. (riscv*-*-freebsd*): Likewise. * config/riscv/t-crtstuff: New file.
