Subject: sim: hoist mn10300 & v850 igen rules up to common builds
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d2a5dbc744548e173ba1687e1a63a8c2196c7122;p=binutils-gdb.git

sim: hoist mn10300 & v850 igen rules up to common builds

These rules don't depend on the target compiler settings, so hoist
the build logic up to the common builds for better parallelization.

We leave the mips rules in place as they depend on complicated
arch-specific configure logic that needs to be untangled first.
