[PATCH] [Gold,MIPS] Detect 64-bit MIPS targets

[PATCH] [Gold,MIPS] Detect 64-bit MIPS targets

[Aurelien Jarno]

When building gold targetting mips64el-linux-gnu or mips64-linux-gnu,
the configure script does not set HAVE_TARGET_64_LITTLE or
HAVE_TARGET_64_BIG. This causes the link of gold to fail:

mips.o: In function `(anonymous namespace)::Target_mips<64, true>::set_gp(gold::Layout*, gold::Symbol_table*) [clone .isra.1854]':
/home/aurel32/git/binutils-gdb/gold/mips.cc:8377: undefined reference to `gold::Sized_symbol<64>::init_output_data(char const*, char const*, gold::Output_data*, unsigned long, unsigned long, elfcpp::STT, elfcpp::STB, elfcpp::STV, unsigned char, bool, bool)'
mips.o: In function `gold::Merged_symbol_value<64>::value(gold::Relobj const*, unsigned int, unsigned long) const':
/home/aurel32/git/binutils-gdb/gold/object.h:1649: undefined reference to `gold::Merged_symbol_value<64>::value_from_output_section(gold::Relobj const*, unsigned int, unsigned long) const'
/home/aurel32/git/binutils-gdb/gold/object.h:1649: undefined reference to `gold::Merged_symbol_value<64>::value_from_output_section(gold::Relobj const*, unsigned int, unsigned long) const'
...

Fix that by adding mips64el and mips64 entry in gold/configure.tgt

gold/Changelog:
	* configure.tgt: Add mips64el*-*-*|mips64le*-*-* and mips64*-*-*.
