CONFIGURE: Add support for host-alias prefixed strings binary.

This is the last outstanding change of patch #1359 - "Update
wii/gamecube configure" submitted on 2010-11-15.
CONFIGURE: Add support for host-alias prefixed strings binary on LE.

This was missed from the Wii patch as the Wii is Big Endian.
CONFIGURE: Fix information output for host-alias-strings test.

Thanks to LordHoto for the amendment to surpress error output.
CONFIGURE: Send output for host-alias-strings test to config.log

This is not critical to build configuration and any problems would
be visible by an incorrect endian test result.
