Log: [PowerPC64LE] Fix gdtoa configurations on LE. gdtoa wins the award for "most outdated endianness naming convention" with its IEEE_8087 vs IEEE_MC68k defines. I had a good chuckle. Update softfloat and arith.h to adjust to BE or LE automatically based on the low level preprocessor defines. Fixes printf/scanf on PowerPC64LE, although there is still a problem lurking regarding Signalling NaNs... Sponsored by: Tag1 Consulting, Inc.
