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.

    20       Add support for the Signal Processing Engine.  This will set up

    21       the toolchain so that it supports the SPE ABI extensions. This

    22       mainly targets Freescale e500 processors.

    23       

    24       Setting this option will append "spe" to the end of your target

    25       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc

    26       configure/build system will know to include SPE ABI support.

    27       It will also automatically add "-mabi=spe -mspe" to your

    28       TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,

    29       so you do not need to explicitly add them.
