so it's part of the distribution (manual.texi includes this file)
   It will be replaced with the correct one from the mysqldoc tree before
   building the distribution
 - removed generation and inclusion of MIRRORS file, since the mirror list
   is no longer part of manual.texi anyway
 - replaced YFLAGS with AM_YFLAGS in sql/Makefile.am to make automake happy
 - Redirect standard error when checking for dpkg-architecture in ltconfig
   to avoid error message showing during configuration


Docs/Makefile.am:
   - added reservedwords.texi (which gets included by manual.texi)
   - removed MIRRORS (mirror list is not part of the manual anymore)
Docs/reservedwords.texi:
   - Updated wording a bit after adding it to the tree
Makefile.am:
   - removed MIRRORS from EXTRA_DIST (it's not part of the manual anymore)
ltconfig:
   - Redirect standard error when checking for dpkg-architecture
     to avoid error message showing during configuration (thanks to
     John Wythe for the patch)
sql/Makefile.am:
   - replaced YFLAGS with AM_YFLAGS to make automake happy
