Only touches download-toolchain-sources.sh and build-toolchain.sh
This does not impact the NDK build scripts themselves and is only
needed to properly package NDK release packages.
This patch modifies the script to be able to build all prebuilt toolchain
binaries in a single call. I.e. if passed a recent toolchain source package
generated with download-toolchain-sources.sh, then it will build both
GCC 4.2.1 and GCC 4.4.0 and place them in the final prebuilt tarball.
We need this because, while we're going to switch to gcc 4.4.0 by default
in a new version of the NDK, the 4.4.0 C++ compiler is more strict about
various constructs and might refuse to build certain sources. An option
will be given to application developers to use 4.2.1 instead, to keep their
sources building.
Other changes include:
Move all builds into a random temporary directory under /tmp by default,
unless you use --build-out=<path>.
Cleanup the build out directory on succesful build
The generated tarball is now named android-ndk-prebuilt-<date>-<host>.tar.bz2
by default, unless you use the new --release=<name> option which will replace
<date> with <name> instead.
Removal of un-needed files (e.g. info or man pages, libiberty static library,
etc..) to reduce the size of the final tarball.
Update the script used to build the prebuilt toolchain binaries.
There are now two ways to use it:
1/ As usual, just invoke it and it will download the source tarball,
uncompress it, configure the toolchain sources, build them, then
package the result into a 'prebuilt' tarball.
2/ Generate a new source tarball with the 'download-toolchain-sources.sh'
script, and invoke build-toolchain.sh with the --package=<tarball>
option.
Additionally, you can now specify --gcc-version=4.4.0 to build GCC 4.4.0
(with ARMv7 / FPU support)
The option --gdb-version=6.8 has been added but the build doesn't seem
to work yet. This will probably be fixed in the toolchain git repository
though.
This will be used to refresh the NDK with gcc 4.4.0 prebuilts and support
for armeabi-v7a soon.
This is used to reduce the number of distributable prebuilt packages
(i.e. linux-x86_64 is not needed anymore).
Also fix build/tools/build-toolchain.sh to properly copy the GPL and LGPL
license files into the generated prebuilt packages.
Also add a .gitignore files to get less spew from 'git status'
