CC_FOR_BUILD is not an autotool convention.  it's specific to whatever package 
actually respects it (i wish it were actually standardized).  whatever package 
you're working with should not add any target build flags to the CC_FOR_BUILD 
steps.  if it does, it's broken, and you need to report the issue to the 
maintainer.  instead, there should be new vars "BUILD_CFLAGS" and 
"BUILD_LDFLAGS" and such.
