The PRU GAS port I originally submitted does not build on 32bit hosts.
This patch fixes it by aligning md_number_to_chars's definition with
the global declaration in tc.h.
Here is the original bug report I got:
https://github.com/rcn-ee/repos/pull/23#issuecomment-269915175
2017-01-02 Dimitar Dimitrov <dimitar@dinux.eu>
gas/
* config/tc-pru.c (md_number_to_chars): Fix parameter to be
valueT, as declared in tc.h
* config/tc-pru.c (md_apply_fix): Fix to work on 32-bit hosts.
