4Subject: [PATCH] or1k: Use cmodel=large when building crtstuff
5
6When linking gcc runtime objects into large binaries the link may fail
7with the below errors.  This will happen even if we are building with
8-mcmodel=large.

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

15This patch builds the gcc crtstuff binaries always with the
16-mcmodel=large option to ensure they can be linked into large binaries.
