If you are running a buildroot inside a VM with many threads you might experience random build failures.
Setup: Host: i7 16GB RAM, VM on Harddisk, Win 7 64bit, VMWare Player Guest: Lubuntu 13.04 64bit 4GB RAM ext4 partition make -j 8
Errors: Build fails like
mv: cannot stat '.deps/dlog.Tpo': No such file or directory or ../libtool: line 46: -c: command not found libtool: Version mismatch error. This is libtool 2.4, but the libtool: definition of this LT_INIT comes from libtool 2.2.6. libtool: You should recreate aclocal.m4 with macros from libtool 2.4 libtool: and run autoconf again.
Cleaning up buildroot helps sometimes, reduce concurrency.
