Here's the next step:

- could you update config.sub and config.guess to the latest version?  That's required for Android support, i.e. the host arm-linux-androidabi, otherwise ./configure dies like this:

  checking host system type... Invalid configuration `arm-linux-androideabi': 
    system `androideabi' not recognized
  configure: error: /bin/bash ./config.sub arm-linux-androideabi failed

- I needed to apply the attached simple patch to get things building since Android does not have SYS_gettid but does define __linux.  It seems to be something in _GNU_SOURCE, so __gnu_linux__ seems an appropriate test.

- the *-config scripts don't seem to work when cross-compiling, since they use prefix= but they don't include DESTDIR, i.e. they assume that the libs are all installed into their final destination.  Or am I missing something?  I'm using ./configure --with-gpg-error-prefix=$(LOCAL) ($LOCAL is the full path, not just the prefix) but that doesn't seem to help because I get:

/bin/sed: can't read /data/data/info.guardianproject.gpg/app_opt/lib/libgpg-error.la: No such file or directory
libtool: link: `/data/data/info.guardianproject.gpg/app_opt/lib/libgpg-error.la' is not a valid libtool archive

I've also tried using sed to replace the prefix= line in each *-config script to the full path, and it also gives a similar error.  But I found that merely running "make -C gpgme" works...
