configure: do not require hg when configuring in an hg clone

When configuring in an hg clone, we need hg to compute the version string.
It can happen that users do not have Mercurial (eg. if they got a snapshot
rather that they did a full clone). In this case, we can still run, of
course, so simply fill the version string with a sufficiently explicit
value, that does not require hg. The date is a good candidate.

     4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch

     5 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,

     6 you have to actually list out the multilibs you want or you will end up with

     7 just one when using targets like 'sh4-linux-gnu'.

     8 

     9 The resulting toolchain can't even build a kernel as the kernel needs to build

    10 with the nofpu flag to be sure that no fpu ops are generated.

    11 

    12 Here we restore the gcc-3.x behavior; the additional overhead of building all

    13 of these multilibs by default is negligible.
