If I understand you correctly you have two options:

1. Instead of -lfoo specify /full/path/to/libfoo.a

2. Something like: -largs -Wl,-Bstatic -lfoo -lbar -Wl,-Bdynamic

The latter will switch the linker to static mode, link in the libraries
you specify and then switch it back to dynamic linking for the rest of
the command line (i.e. the part that gets added automatically for the
GNAT runtime etc).

Note also that the latter will probably only work on systems that have
the GNU linker and you may have to replace -Bstatic and -Bdynamic by
something else on other (i.e. non-Linux) OSes.
