AIX/gcc fixes.

Browse Source 
- Use native AIX linker
        - Search both for .a and .so libraries
        - Include only solib basename to refer to them, to workaround for lack
        for -soname option.

Patches from Andrew Miller and Andrej van der Zee.

#
# On AIX we *have* to use the native linker.
#
# Using -brtl, the AIX linker will look for libraries with both the .a and .so
# extensions, such as libfoo.a and libfoo.so. Without -brtl, the AIX linker
# looks only for libfoo.a. Note that libfoo.a is an archived file that may
# contain shared objects and is different from static libs as on Linux.
#
# The -bnoipath strips the prepending (relative) path of libraries from
# the loader section in the target library or executable. Hence, during load-
# time LIBPATH (identical to LD_LIBRARY_PATH) or a hard-coded -blibpath
# (*similar* to -lrpath/-lrpath-link) is searched. Without this option,
# the prepending (relative) path + library name is hard-coded in the loader
# section, causing *only* this path to be searched during load-time.
# Note that the AIX linker does not have an -soname equivalent, this
# is as close as it gets.
#
# The above options are definately for AIX 5.x, and most likely also for
# AIX 4.x and AIX 6.x. For details about AIX linker:
