MIPS: fix building on multiarch platform
On platforms that support multiarch, such as Debian,
the filesystem hierarchy doesn't fellow the old Irix style:
lib & lib/<multiarch> for native
lib64 for N64 on N32/O32 systems
lib32 for N32 on N64/O32 systems
libo32 for O32 on N64/N32 systems
Thus we cannot
#define STANDARD_STARTFILE_PREFIX_1
#define STANDARD_STARTFILE_PREFIX_2
on N32 or N64 systems, else collect2 won't look for libraries
on /lib/<multiarch>.
gcc/ChangeLog:
* configure.ac: AC_DEFINE(ENABLE_MULTIARCH, 1)
* configure: Regenerated.
* config.in: Regenerated.
* config/mips/mips.h: don't define STANDARD_STARTFILE_PREFIX_1
if ENABLE_MULTIARCH is defined.
* config/mips/t-linux64: define correct multiarch path when
multiarch is enabled.
