compiled with gcc 5.3, using softfloat.

>Description:

awk misbehaves, when running postinstall on a freshly installed system
it says:

obsolete check:
        Remove obsolete file /usr/lib/libgomp.so.1.2
        Remove obsolete file /usr/lib/libstdc++.so.7.4

This happens because the awk script uses the wrong branch in postinstall::601:

		res = digit(orev, orevc, i) - digit(nrev, nrevc, i)
		if (res < 0) {
			print LibDir lib results[lib]
			results[lib] = rev
			return
		} else if (res > 0) {
			print LibDir lib rev
			return
		}

where digit returns the tiny number to differentiate (the "2" in libgomp.so.1.2
versus "1" in libgomp.so.1.1), so 2 is newer, res is -1 but it still goes into
the lower else if (res > 0).

>How-To-Repeat:
s/a
>Fix:
n/a
