Patch to configure in which I fixed the problem about building the Debian
packages on ia64, and a mistype that prevented Clarens from being build
on Debian. Also, I changed the `check_symbol' function. First of all, it
would always fail if the library was in `/usr/lib' as that was never
prepended to the file name. Secondly, it would always fail if you had a
stripped shared library, which is the common thing if the library is in
`/usr/lib'. I introduced a test that uses the compiler/linker (via
`config/Makefile.<arch>') to do a simple test program that calls the
specified function, and then tries to link to the specified library.
If that succeeds, the test succeeds. Note, this is more or less what
Autoconf does for you.
Plus added the template `build/misc/html.C.in' which will generate
`macros/html.C' according to the optional packages that were built.
