Add glibc2.15-based host toolchain.
Build instructions:
MYGCCBIN="`pwd`/../x86_64-linux-glibc2.11-4.8/bin"
CC=$MYGCCBIN/x86_64-linux-gcc \
CXX=$MYGCCBIN/x86_64-linux-g++ \
./build-precise-multilib-toolchain.sh \
--work-dir=$MYWORKDIR
After build:
* Add symbolic link:
sysroot/usr/include/stdatomic.h
* Copy from precise (12.04):
/usr/lib/i386-linux-gnu/libxcb.so.1.1.0
/usr/lib/i386-linux-gnu/libxcb.so.1 -> libxcb.so.1.1.0
/usr/lib/x86_64-linux-gnu/libxcb.so.1.1.0
/usr/lib/x86_64-linux-gnu/libxcb.so.1 -> libxcb.so.1.1.0
to
sysroot/usr/lib32/libxcb.so.1.1.0
sysroot/usr/lib32/libxcb.so.1 -> libxcb.so.1.1.0
sysroot/usr/lib/libxcb.so.1.1.0
sysroot/usr/lib/libxcb.so.1 -> libxcb.so.1.1.0
