Hardly. :-)

The problem is exceedingly challenging.  You did not mention that on 
some systems libraries need to be listed in a (particular) order of 
diminishing dependency.  For example, -lm and -lpthread would 
typically appear at the end of the dependency list.

Autotools has a policy of allowing the person running configure to 
specify additional configuration information via CFLAGS, LDFLAGS, 
and LIBS.  This mechanism should not be broken.
