When building with --disable-static on AIX, linking various binaries
that call syscall() currently fail:
/bin/sh ../../libtool --quiet --mode=link --tag=CC
/opt/IBM/xlC/16.1.0/bin/xlc_r -static [...] -o afsd afsd.o afsd_kernel.o [...]
ld: 0711-317 ERROR: Undefined symbol: .syscall
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
make: The error code from the last command is 8.
There is indeed no symbol 'syscall', because that is a
(confusingly-named) syscall provided by our libafs kernel module. To
tell the linker that syscall() is a syscall, import our afsl.exp by
passing the -Wl,-bI: flag to the linker for all binaries that call it.
To make it easier to see what's going on, add the AIX_ONLY subst var, to
make it easy to create an AIX-only line in the relevant Makefiles.
