winegcc: Add --wine-objdir and --winebuild options for the Wine build. 

This avoids overloading the meaning of the -B and --sysroot options.

.B gcc options:
All gcc options are supported, and are passed along to the backend
compiler.
.IP "\fB-B\fIprefix\fR"
This option specifies where to find the executables, libraries,
include files, and data files of the compiler itself. This is a
standard gcc option that has been extended to recognize a
\fIprefix\fR ending with '/tools/winebuild', in which case winegcc
enters a special mode for building Wine itself. Developers should
avoid prefixes ending with the magic suffix, or if that is not
possible, simply express it differently, such as '/tools/winebuild/',
to avoid the special behaviour.
.IP "\fB-b,--target \fItarget\fR"
Specify the target architecture triplet for cross-compiling. winegcc
will then invoke \fItarget\fR-gcc instead of gcc.
.IP "\fB--wine-objdir \fIdir\fR"
Specify the Wine object directory. This is used when building Wine
itself, to use the includes and libraries from inside the build tree.
.IP "\fB--winebuild \fIname\fR"
Specifies the path and name of the \fBwinebuild\fR binary that will be
launched automatically by \fBwinegcc\fR. If not set, \fBwinegcc\fR
will look for a file named \fIwinebuild\fR in the path. This takes
precedence over the \fBWINEBUILD\fR environment variable.
