Hang on, have I done something evil there? I'm working on another package now
and these flags are leaking into it. Looks like apending to TARGET_CFLAGS is
a no-no. So the rule to follow is: all Make macros should be scoped with the
package name. What I wanted to do was add to the value of CFLAGS as passed
by TARGET_CONFIGURE_OPTS. I'm looking for the right way to do that...

Steve.
