Hi, Bernhard
Have not tried to compile with the INCLUDE_PERF=1.
just a question here.
as Marcus said, we only have the libc-version.h in following 3 places,
marcus@dwarf1:~/linaro-13.03-src/android$ find . | grep libc-version.h
./prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.7-4.6/sysroot/usr/include/gnu/libc-version.h
./prebuilts/gcc/linux-x86/host/i686-linux-glibc2.7-4.6/sysroot/usr/include/gnu/libc-version.h
./prebuilts/gcc/linux-x86/host/i686-linux-glibc2.7-4.4.3/sysroot/usr/include/gnu/libc-version.h
