Originally, there are _rand48 (in libc/bionic/_rand48.c) and __rand48 (in libc/stdlib/_rand48.c) implemented in bionic. Besides the naming, the functionality is identical. This patch removes the duplicated _rand48. Also, drand48 and erand48 are modified accordingly. Change-Id: Ie5761a0a97f45df8538222a77edacb7c3e0125d7
