config.mak.uname: set NO_REGEX=NeedsStartEnd on AIX

Browse Source 
Set the NO_REGEX=NeedsStartEnd Makefile flag by default on AIX.

Since commit 2f8952250a ("regex: add regexec_buf() that can work on a
non NUL-terminated string", 2016-09-21) git has errored out at
compile-time if the regular expression library doesn't support
REG_STARTEND.

While looking through Google search results for the use of NO_REGEX I
found a Chef recipe that set this on AIX[1], looking through the
documentation for the latest version of AIX (7.2, released October
2015) shows that its regexec() doesn't have REG_STARTEND.
