libXau 1.0.3 Makefile.am patch

If I run "make -n" in the libXau directory, I get the following error:

[...]

/bin/sh ./libtool  --tag=CC --mode=link gcc -Wall -Wpointer-arith -Wstrict-prototypes 	-Wmissing-prototypes -Wmissing-declarations 	-Wnested-externs -fno-strict-aliasing    -g -O2   -o libXau.la -rpath /usr/local/lib -version-number 6:0:0 -no-undefined AuDispose.lo AuFileName.lo AuGetAddr.lo AuGetBest.lo AuLock.lo AuRead.lo AuUnlock.lo AuWrite.lo

make[1]: *** No rule to make target `XauFileName.3', needed by `all-am'.  Stop.
make[1]: Leaving directory `/tmp/libXau-1.0.3'
make: *** [all] Error 2

Then, if I look at Makefile.am, there is not rule for those files, only a "shadows.DONE" rule creating the needed files.
In addition, this shadows.DONE rule is just a shell loop, so it's really something that can be done with Makefile rules, with multiple benefits: rules requiring those files will not fail, make -n will not fail, and it'll be possible to create those files in parallel (but the speed is not really an issue).

See the attached patch, which provide a simple rule to create those files instead of using the shadows.DONE rule.
