The documentation seems to miss an option - please try do add
ASFLAGS="-xarch=v9" to the configure line.

No, it seems like the configure script simply passes all compile flags to
the assembler, if you use "--enable-assembler" and do not define ASFLAGS.
That actually might be a bug in the configure script, but I am not sure.

Yes, please use ASFLAGS as noted above.

Sorry, I can't tell you. We do use assembler functions for some string
operations (see the "strings" subdirectory), but I don't know how
intensively these are being used.
