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.

ARMV5 can use STRD and LDRD access instructions but these accesses need to be 
jocke@1737
     5
8 byte aligned. The dynamic linker's malloc needs to match this so structures

     6
become 8 byte aligned to void unaligned accesses.
