 - added the glibc32 subpackage
 - updated fakesyscall handling scheme
 - added all disabled syscalls to fakesyscall list
 - added new syscalls to fakesyscall list
 - disabled removal of old locales in `locale-gen`
 - implemented syslog function, which is configured to work with the android log system
 - implemented analog variables `LD_*` to customize glibc environment without affecting bionic environment
