[Bug 411890] [NEW] karmic: Compiling php fails with autoconf 2.64

Binary package hint: php5

On a fresh 9.10 (karmic) system, php5 (5.2.10) source package will not compile.
./configure fails with "cat: confdefs.h: No such file or directory"

Steps:

# Install brand new Ubuntu karmic release (alpha 3)
sudo pbuilder --create --distribution karmic
dget -xu https://launchpad.net/ubuntu/karmic/+source/php5/5.2.10.dfsg.1-1ubuntu1/+files/php5_5.2.10.dfsg.1-1ubuntu1.dsc
cd php5_5.2.10.dfsg.1/
pdebuild -- --distribution karmic

cat: confdefs.h: No such file or directory
../configure: 488: ac_fn_c_try_run: not found
../configure: 488: 5: Bad file descriptor
../configure: 488: :: checking for pthreads_cflags: not found
../configure: 488: 6: Bad file descriptor

This error has been reproduced many times on the build farm, and also
independently on 2 developer's machines. Build log attached.

This source package can be compiled successfully on jaunty (after
resolving php5.2.10 dependencies), with no such errors. The build logs
between karmic and jaunty looks almost identical.

Examination of the build area afterwards shows that the 'condefs.h' file
do exist in the apache2-build diectory however, the ./configure script
is a complete mess, after being regenerated with a different version of
autoconf (2.64 instead of 2.13 although Jaunty also has a different
autocond which is 2.63). This error appears to be caused somewhere
around the 'buildconf --force' stage in the rules file. At a time when
"./configure" is being regenerated.

So I compared with those older Successful build logs from the build
farm. Side-by side there's only 2 lines different:

Success log:

buildconf: checking installation...
buildconf: autoconf version 2.63 (ok)
buildconf: Your version of autoconf likely contains buggy cache code.
           Running cvsclean for you.
           To avoid this, install autoconf-2.13.

configure.in:463: warning: AC_CACHE_VAL(have_broken_glibc_fopen_append, ...): suspicious cache-id, must contain _cv_ to be cached

Fail log:

buildconf: checking installation...
buildconf: autoconf version 2.64 (ok)
buildconf: Your version of autoconf likely contains buggy cache code.
           Running cvsclean for you.

This package was originally build when karmic has autoconf 2.63. Now
karmic is autoconf 2.64 then php5 will fail to build. (I am unsure what
is the correct resolution for this.)
