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

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