Add support for Bionic C library
gcc/
* config.gcc (LIBC_GLIBC, LIBC_BIONIC, LIBC_UCLIBC): New tm_define
macro.
(DEFAULT_LIBC): New tm_define macro set to one of LIBC_*.
(bfin*-uclinux, moxie-*-uclinux*, m68k-*-uclinux*): Update.
* config/linux.h (OPTION_GLIBC, OPTION_UCLIBC, OPTION_BIONIC): Define.
(LINUX_TARGET_OS_CPP_BUILTINS): Define __gnu_linux__ only for GLIBC.
(CHOOSE_DYNAMIC_LINKER1, CHOOSE_DYNAMIC_LINKER): Make it easier
to support multiple C libraries. Handle Bionic.
(BIONIC_DYNAMIC_LINKER, BIONIC_DYNAMIC_LINKER32,)
(BIONIC_DYNAMIC_LINKER64): Define.
(LINUX_DYNAMIC_LINKER, LINUX_DYNAMIC_LINKER32, LINUX_DYNAMIC_LINKER64):
Update.
(TARGET_HAS_SINCOS): Enable for Bionic.
* config/linux.opt: Rewrite to handle more than 2 C libraries. Make
the last option specified on command line take effect.
(linux_uclibc): Rename to linux_libc, initialize using DEFAULT_LIBC.
(mbionic): New.
(mglibc, muclibc): Update.
* config/alpha/linux-elf.h, config/rs6000/linux64.h,
