mesa3d: use -mno-compact-eh for Code Sourcery MIPS

Browse Source 
mesa3d doesn't like the new compressed exception handling of the Code
Sourcery MIPS toolchain and it fails to compile with an error like this
one:

/br/output/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/5.3.0/../../../../mips-linux-gnu/bin/ld:
../../../../src/mesa/.libs/libmesagallium.a(ir_to_mesa.o):
.eh_frame_entry not in order
/br/output/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/5.3.0/../../../../mips-linux-gnu/bin/ld:
final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status

Using -mno-compact-eh fixes the problem.
