[PATCH 0/3] configure.ac: misc configure fixes

[Andreas Herrmann]

Some of the configure options are not working as expected.
I first encountered this when using '--with-expat=no'.
Following patches address this.

I've also checked configure options for 'libpcre', 'openssl' (together
with 'make OPENSSL_SHA1=yes ...'), and 'tcltk'. These are working
correctly.

As a test I've run 'make test' when disabling support of a package.
I always had to use 'export GIT_SKIP_TESTS="t5801.1[4-7] t5801.31"' to
skip some failing tests. Those failed also with default build.

When disabling iconv ('configure --without-iconv') further tests are
failing. In this case I've used
'export GIT_SKIP_TESTS="t5801.1[4-7] t5801.31 \
t0028* t2082.2 t3434* t390[01]* \
t4041* t4059* t4060.8 t4201.12 t4205* t4210* t4254.[34] \
t5100* t6006* t7102.2 t8005* t9300.193 t9350*"'
to ensure that 'make test' completed without exiting early.

  configure.ac: don't overwrite NO_CURL option
  configure.ac: always save NO_ICONV to config.status

[PATCH 1/3] configure.ac: don't overwrite NO_EXPAT option

[Andreas Herrmann]

Even if 'configure --with-expat=no' was run, expat support is used,
because library detection overwrites it. Avoid this overwrite.
Configure should obey what the user has specified.

[Andreas Herrmann]

Even if 'configure --with-curl=no' was run, curl support is used,
because library detection overwrites it. Avoid this overwrite.

[PATCH 3/3] configure.ac: always save NO_ICONV to config.status

[Andreas Herrmann]

In case 'configure --with-iconv=no' is used, NO_ICONV is not saved to
config.status and thus git is built with iconv support.

Always save NO_ICONV to config.status to honor what user selected
during configure step.

All patches look good.

Thanks, will queue.
