Hi,
This patch prevents optimizing libraries for space from overriding all
previous CFLAGS_FOR_TARGET settings. Add optimization flags to any
pre-existing values.
I hit this problem whilst building a Gcc cross compiler and newlib
library for ARM with crosstool-NG-1.20.0. The newlib developers
suggested I should try posting it here.
