[v3] let doxygen find generated header files

[Jonathan Wakely]

I think part of the suggestion in this mail:

http://gcc.gnu.org/ml/libstdc++/2004-11/msg00080.html

might prevent doxygen finding the headers in the host_alias directory,
as run_doxygen is called with an empty host_alias value:

[redi@morion libstdc++-v3]$ make doxygen-man
(srcdir=`cd ../../../gcc-4.x/libstdc++-v3; ${PWDCMD-pwd}`; \
  builddir=`${PWDCMD-pwd}`; \
  /bin/sh ../../../gcc-4.x/libstdc++-v3/docs/doxygen/run_doxygen \
            --host_alias=${host_alias} \
            --mode=man ${srcdir} ${builddir})
:: Using Doxygen tools from /home/redi/bin.
../../../gcc-4.x/libstdc++-v3/docs/doxygen/run_doxygen: line 119: test: =: unary operator expected
:: NOTE that this may take some time...

I think the fix is to set host_alias in the shell command, as srcdir and
buildir are, or remove a few $s from Makefile.am, as this patch does.
