Description:

When building some 32 bit programs on an x86_64 system (namely, Android images based on the AUR android-sdk package), the following error occurs.

host Executable: acp (out/host/linux-x86/obj/EXECUTABLES/acp_intermediates/acp)
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-unknown-linux-gnu/4.5.1/libgcc.a when searching for -lgcc
/usr/bin/ld: cannot find -lgcc
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/acp_intermediates/acp] Error 1

Only the 64 bit version of libgcc.a is found. It comes with gcc-4.5.1-1. For the sake of completeness, shouldn't libgcc.a for 32 bit platforms come with lib32-gcc-libs?

Additional info:
* local/gcc-libs 4.5.1-1 (base)
* local/lib32-gcc-libs 4.5.1-7
(Example:
* local/repo-git 20101124-1
* local/android-sdk r07-1
)

Steps to reproduce:
* Install repo-git and android-sdk from AUR on an x86_64 machine (changing python calls to use pyton2 when there are failing scripts)
* repo init -u git://android.git.kernel.org/platform/manifest.git; repo sync
* make
