JDK-8079891 caused this behavior:
/scratch/dh198349/jdk9-dev > mkdir mybuild
/scratch/dh198349/jdk9-dev > cd mybuild
/scratch/dh198349/jdk9-dev/mybuild > bash ../configure

With JDK-8079891, a new file, configure.log will be present in the
current directory, and this file is not filtered out when checking if
the directory is (otherwise) empty. Introspection shows that running
"configure --debug-configure" in an empty directory has probably been
failing for a long time.
I also took the liberty of removing fixpath.exe from the filters, since
fixpath is (nowadays) created much later in the configure process (and
stored in a different place), and replacing tabs with spaces.
