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.

GCC trunk now has multiple internal headers directories, one
yann@1004
     2
containing the self-contained GCC-provided headers and one containing
yann@1004
     3
the <limits.h> (not self-contained but including libc's <limits.h> or
yann@1004
     4
a fixed version thereof) and the fixed headers; more such directories
yann@1004
     5
may be added in future.

When glibc uses -nostdinc, it needs to use -isystem options for all
yann@1004
     8
these internal directories.  This patch teaches it about the
yann@1004
     9
include-fixed directory (and is harmless with old GCC versions without
yann@1004
    10
that directory).
