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.

Without this patch, the sec script that processed initfini.s removes a
yann@1625
     8
part of inlined call_gmon_start, causing undefined label errors.

This patch solves the problem by forcing gcc not to inline
yann@1625
    11
call_gmon_start with __attribute__ ((noinline)).
