Adhemerval Zanella 30c1dfde31 string: Improve generic stpcpy 
It follows the strategy:

  - Align the destination on word boundary using byte operations.

  - If source is also word aligned, read a word per time, check for
    null (using has_zero from string-fzb.h), and write the remaining
    bytes.

  - If source is not word aligned, loop by aligning the source, and
    merging the result of two reads.  Similar to aligned case,
    check for null with has_zero, and write the remaining bytes if
    null is found.

Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64-linux-gnu,
and powerpc-linux-gnu by removing the arch-specific assembly
implementation and disabling multi-arch (it covers both LE and BE
for 64 and 32 bits).
