[libxml++] Portability patches for 1.0.1

[Albert Chin <libxmlplusplus-general mlists thewrittenword com>]

The patches below were required to get libxml++ build using the Sun,
HP, SGI, and AIX C++ compilers.

Why do you add @LIBXML_LIBS@ to Libs: in libxml++-1.0.pc.in? Why not
add libxml-2.0 to the Requires: line? pkg-config will do the right
thing and search for libxml-2.0.pc.

Also, libtool 1.5.x won't correctly build libxml++ using the Sun C++
compiler. I've submitted a patch to libtool-patches gnu org so
hopefully it'll make it into 1.5.3. The problem is that convenience
libraries are not passed correctly to the linker so all the symbols
from the convenience libraries don't make their way into libxml++.so.
