* config.gcc (powerpc*-*-*): Add support for a new configure
option --with-advance-toolchain=<xxx> which overrides using the
default header files, libraries and dynamic linker.
* config/rs6000/linux64.h (SUBSUBTARGET_EXTRA_SPECS): Add new
specs to support the configure --with-advance-toolchain=<xxx>
option.
(INCLUDE_EXTRA_SPEC): Likewise.
(LINK_OS_EXTRA_SPEC32): Likewise.
(LINK_OK_EXTRA_SPEC64): Likewise.
(LINK_OS_NEW_DTAGS_SPEC): Likewise.
(DYNAMIC_LINKER_PREFIX): Likewise.
(CPP_OS_DEFAULT_SPEC): Use the new specs for providing advance
toolchain support.
(GLIBC_DYNAMIC_LINKER32): Likewise.
(GLIBC_DYNAMIC_LINKER64): Likewise.
(LINK_OS_LINUX_SPEC32): Likewise.
(LINK_OS_LINUX_SPEC64): Likewise.
* doc/install.texi (--enable-advance-toolchain=<xx>): Document new
configuration option.
