checking for sysroot...no

when the toolchain *does* support sysroots.  Basically, if sysroot.at
can't figure out both the sysroot AND the prefix *under* the sysroot, it
skips the test (I think this is the right behavior).

The problem was that cygwin doesn't have crt1.o, crt2.o, or crti.o, so
all of the attempts to determine the prefix failed.
