Define L_ENDIAN for linux64-loongarch64

In commit d7c0fc5b1a7b5cb2219f8d89a861f3879582fc16 we removed L_ENDIAN
definition for guessed linux64-loongarch64 as it had caused an
inconsistency between configurations with and without explicit
specifying linux64-loongarch64.  Now add it back to the proper location.

Unlike MIPS or RISC-V, LoongArch is always little-endian [1].

By the way, change "LOONGARCH" to "LoongArch" in a comment as LOONGARCH
should only appear in the identifiers of macros, constants, etc.
