I've only changed the following:

There's no arm port because of lack of testing.
ARM is even more complicated than MIPS. There are multiple targets
for
ARM and there is soft float and hard float and probably a
combination.
It' s not cut and dry to add to the main cross-lfs book. If someone
can
give all of the options for build flags and for target and build for
most arm options, then maybe. I don't have arm hardware to test.
Your
configuration may work, but not for all arm devices. Arm isn't for
the
weak.
The vast number of combinations are fairly well documented for 32 bit
ARM in embedded [1]. Granted, this is for musl toolchains and not
glibc-based, but the floating point and arch portions are the same
regardless of libc choice.

GCC defaults to aapcs-linux for EABI now, OABI is basically dead I'm
told.

It is going to take an arm and a leg.
