Your Makefile is correct, except that it calls the C compiler to link
your program.  If you call gnatgcc instead, you should be fine.  By
default, gnatgcc looks in /usr/lib/gcc-lib/i486-linux/2.8.1/adalib,
but gcc (the C compiler) only looks in /usr/lib.

Adding another symlink in /usr/lib is also an option.
