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)

     3   I'm still working on the solaris port an I have the same issue here.

     4   While trying to build the i686-nptl-linux-gnu toolchain under

     5   OpenSolaris, the problems appears during the make install rule of the

     6   libc function.

     7 

     8   The problem is that solaris tries to execute ld-linux.so.2, which is an

     9   elf 32 bits dyn lib, and it fails with a memory fault, not a "cannot

    10   execute binary file". Hence the build stops on this error.

    14   After digging a little, the problem comes from the

    15   glibc-2.6.1/posix/Makefile. It has been solved starting from glibc 2.7

    16   so I extracted a patch for glibc 2.6.1.
