 .la files are automatically generated text files that contain linking
 information. muniversal group fails if two .la files differ.

 However, it seems we could apply some heuristics, for example with the
 dependency_libs key.

 i386 and x86_64 libgettextlib.la files are identical except for the
 following line:

 {{{
 # Libraries that this one depends upon.
 dependency_libs=' /opt/local/lib/libintl.la -L/opt/local/lib -lc
 -ltermcap'
 }}}

 {{{
 # Libraries that this one depends upon.
 dependency_libs=' -R/opt/local/lib /opt/local/lib/libintl.la
 -L/opt/local/lib -lc /opt/local/lib/libiconv.la -lncurses'
 }}}

 That these lines could probably be merged by putting every item in each,
 and that wouldn't create a problem. The attached patch does just this and
 allows gettext +universal to be built on 10.6.

 The patch could be extended to process inherited_linker_flags as well (see
 ticket #22801).

 What do you think?
