[PATCH:libXaw3d] Add xext to required modules for Shape extension calls

[Alan Coopersmith]

Without this, strict linkers like Solaris ld & gold would fail with:

Undefined                       first referenced
 symbol                             in file
XShapeQueryExtension                .libs/Command.o  (symbol belongs to implicit dependency libXext.so.0)

I'm assuming gold would give similar errors, based on past reports/patches
and http://wiki.debian.org/ToolChain/DSOLinking , but I didn't try it.
