scripts: refine static linking check to better guide the user

The current mechanism to check if static linking is possible, and the mesage
displayed on failure, can be puzzling to the unsuspecting user.

Also, the current implementation is not using the existing infrastructure,
and is thus difficult to enhance with new tests.

So, switch to using the standard CT_DoExecLog infra, and use four tests to
check for the host compiler:
- check we can run it
- check it can build a trivial program
- check it can statically link that program
- check if it statically link with libstdc++

That should cover most of the problems. Hopefully.

(At the same time, fix a typo in a comment)

     9 Hi Robert,
    10 
    11 I've attached two patches:
    12 
    13 1/  For crosstool-0.31 which changes the CYGWIN_URL to one which has the
    14 cygwin source archives.  The version of cygwin that is used to build the
    15 cross toolchain has been changed to cygwin-1.5.15-1-src.tar.bz2 since
    16 most of the mirror sites don't seem to have the original archive used.
    17 [created gcc-3.3.2-cygwin-1.5.15-1.dat - dank]
    18 
    19 
    20 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:
    22 cannot find -luser32
    23 
    24 unless the second patch is applied,
    25
