0bd3559405
- updated to 2.41
- added the glibc32 subpackage
- updated fakesyscall handling scheme
- moved 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 ('GLIBC_LD_*')
- improved source code for flexible glibc compilation
