I am not entirely sure this patch is at fault (I will double check) but
this morning when I tried to build a cross linker (running on x86 linux
and targetting mips-mti-linux-gnu) I got this failure during the ld
configure:
checking whether ANSI C string concatenation works... yes
checking size of void *... 8
/scratch/sellcey/repos/sim-bug/src/binutils/ld/configure: unhandled
emulation
make: *** [configure-ld] Error 1
Error: Make command failed, stopping build.
Has anyone else seen this?
