[patch] lib/autoconf/specific.m4: turn AC_ISC_POSIX into a NOP |

Mutt/1.5.21 (2010-09-15) |
The platform that needed it saw it's last release in 1998,
is completely unsupported since 2006, and it was already
documented that new programs need not use AC_ISC_POSIX.
The main objective of this change is that without it autoupdate
turned AC_ISC_POSIX into AC_SEARCH_LIBS([strerror],[cposix])
in configure.ac, keeping this zombie alive forever.
