gcc
gcc is the backbone, but in my experience you need the whole Android ecosystem installed in order to compile anything. You can download it all from http://developer.android.com/index.html

.. in fact there are some precompiled arm-eabi gcc s lurking in prebuilt/ that
it uses for most stuff. Android is a bit weird about its executables
(for a few quite good reasons), but should get on moderately well with
most gcc s if you fettle them appropriately.
The main thing to do is to make sure that you're not using a glibc
gcc, else it will (unsurprisingly) probably fight bionic.

which in this case means adding all the bionic patches, then you might
as well use the google provided ones.

yep 
If you don't want to compile a OS image but just a program or two the
NDK works as well.
Much easier to get started was well.
