Stafford Horne da8a9d695b or1k: Use cmodel=large when building crtstuff
When linking gcc runtime objects into large binaries the link may fail
with the below errors.  This will happen even if we are building with
-mcmodel=large.

    /home/shorne/work/openrisc/output/host/lib/gcc/or1k-buildroot-linux-uclibc/10.3.0/crtbeginS.o: in function `deregister_tm_clones':
    crtstuff.c:(.text+0x3c): relocation truncated to fit: R_OR1K_GOT16 against undefined symbol `_ITM_deregisterTMCloneTable'
    /home/shorne/work/openrisc/output/host/lib/gcc/or1k-buildroot-linux-uclibc/10.3.0/crtbeginS.o: in function `register_tm_clones':
    crtstuff.c:(.text+0xc0): relocation truncated to fit: R_OR1K_GOT16 against undefined symbol `_ITM_registerTMCloneTable'

This patch builds the gcc crtstuff binaries always with the
-mcmodel=large option to ensure they can be linked into large binaries.

libgcc/ChangeLog:

	PR target/99783
	* config.host (or1k-*, tmake_file): Add or1k/t-crtstuff.
