Can we decide to:
1. On AIX systems that support run-time-linking, make it the
*default* so lib<name>.a is "static" and lib<name>.so is
shared. With this, "-brtl" would be "inserted" automatically
into the compile/link phases.
2. On AIX systems that do not support run-time-linking, support
only shared libraries (so, lib<name>.a is shared and there is
no lib<name>.so).
I'm trying to fix the remaining 'make check' failures on AIX and
knowing what to do about shared/static would certainly help. While the
above doesn't expose the full "robustness" of the AIX linker, methinks
it good enough.
