  First of all, please don't top-post, but cut down the quoted message to

  If setting $(TARGET_CONFIGURE_OPTS) in the environment doesn't work, 
then you can try setting it on the command line instead. If that doesn't 
work either, it indicates that something funny is done in the Makefile 
and it's important to find out what exactly. Probably it's a matter of 
CFLAGS or LDFLAGS that need to be set, but are now overridden from the 
command line.

  In that case, the best option is to fix the Makefile (and upstream the 
fix). A less preferred option is something like:


i.e. use the command line to force CC and LD and pass the things that the 
Makefile needs to have control over (CFLAGS and LDFLAGS) through the
