Not really.  This kind of thing crops up pretty regularly when trying to 
produce portable binaries.

For portability, you'll need to generate code for some 
least-common-denominator architecture.

Take a look at the -mtune and -march options in the GCC documentation, as 
well as the "-mmmx" family of options.  Also, look at "configure --help" 
for glib (and other libraries you intend to distribute) for any --enable 
options that relate to architecture-specific instructions.
