debug/gdb: Fix compilation for Mingw hosts

GDB requires PDcurses instead of ncurses while running on Windows.
So, do not always compile ncurses in case GDB needs to build.

PDcurses is provided by an earlier build step and is not described in
this file.

Hi Robert,

I've attached two patches:
yann@402
    12
yann@402
    13
1/  For crosstool-0.31 which changes the CYGWIN_URL to one which has the
yann@402
    14
cygwin source archives.  The version of cygwin that is used to build the
yann@402
    15
cross toolchain has been changed to cygwin-1.5.15-1-src.tar.bz2 since
yann@402
    16
most of the mirror sites don't seem to have the original archive used.

2/ The later cygwin source archive fails to cross build with the error:

    21
/opt/crosstool/i686-pc-cygwin/gcc-3.3.2-cygwin-1.5.15-1/lib/gcc-lib/i686-pc-cygwin/bin/ld:

cannot find -luser32
