Bug Description

Currently, CLooG/PPL is not installed in Android toolchain (android/toolchain/build), and we can only pre-install these packages in advance. However, it causes a problem that we might have different configurations for GNU Toolchain.

The right way is to implement CLooG/PPL support in Android toolchain build process.

It seems that cloog-ppl-0.15.10 has some libtool related bug while --disable-shared:

Linaro/android/toolchain/build$ ldd ./temp-install/bin/arm-eabi-cloog
libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0x00157000)
libcloog.so.0 => /home/jserv/Linaro/android/toolchain/build/temp-install/lib/libcloog.so.0 (0x008d9000)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0x0017d000)
/lib/ld-linux.so.2 (0x0089a000)
libgcc_s.so.1 => /lib/i386-linux-gnu/libgcc_s.so.1 (0x00110000)

It should not produce any shared library and the linkage is wrong.

To make static link work, we have to make sure CLooG-parma in LIBS list.
