pnacl: move libgcc compiler flags into utman

compiler-rt/lib/Makefile-pnacl

 # This Makefile builds onacl version of libgcc.a
 #
 # More information on the functions of libgcc can be found at:
 # http://gcc.gnu.org/onlinedocs/gccint/Libgcc.html#Libgcc
 # ../README.txt
 #
 # The following variables are expected to be set externally:
 
 # SRC_DIR
 # ARCH

[jvoung - send to chromium..., 2011/06/20 21:10:02]

ARCH no longer needed?

[robertm, 2011/06/20 21:16:06]

just fixed that - it will eventually be obsolete

[jvoung - send to chromium..., 2011/06/20 23:06:41]

So, what is the outcome? Cleanup now, or no?

[robertm, 2011/06/20 23:17:14]

will clean this up before submitting
