I know that in CLFS-1.x for MIPS multilib -mabi=32, -mabi=n32, and -mabi=64 
are used to build the diferent library flavours.

What I don't know and isn't clear in the cross-tools/common/abi.xml CLFS 
Embedded page is what of them must be used for each MIPS processor type 
listed in the table found in cross-tools/mips/variables.xml.

I need be sure that in jhalfs the proper ABI value is selected for the choosen 
target-triple for both MIPS and x86 archs.

At this moment we have this:

 config ABI
  string
  depends BOOK_CLFS3
  default "-m32"  if DATA_32 &&  ARCH_X86
  default "-m64"  if DATA_64 &&  ARCH_X86
  default "-mabi=32" if DATA_32 &&  ARCH_MIPS && PROC_mipsel
  default "-mabi=64" if DATA_64 &&  ARCH_MIPS && PROC_mipsel
  default "-mabi=n32" if DATA_32 &&  ARCH_MIPS && PROC_mips
  default "-mabi=n64" if DATA_64 &&  ARCH_MIPS && PROC_mips

I think that -m64 isn't supported yet by the book and that some of the MIPS 
settings are wrong.

CLFS Embedded support at this momment x86_64 or not?

That page says that all that ABIs sucks, but now how or when use it.
