[PATCH 2/8] winsup/doc: Fix xidepend to handle relative pathnames

[Jon TURNEY <jon.turney@dronecode.org.uk>]

It seems that xidepend doesn't work correctly if we are ./configure'd using a
relative pathname to the srcdir:

$ make
cd ../../../../src/winsup/doc && ./xidepend ../../../../src/winsup/doc/cygwin-ug-net.xml ../../../../src/winsup/doc/cygwin-api.xml >"/wip/cygwin/build/x86_64-unknown-cygwin/winsup/doc/Makefile.dep"
grep: ../../../../src/winsup/doc/cygwin-ug-net.xml: No such file or directory
grep: ../../../../src/winsup/doc/cygwin-api.xml: No such file or directory

Although it might be better to fix this by making xidepend use pathnames, rather
than ignoring them and assuming everything is in the current directory...
