arm.h has had this error message since 1997, and was never updated to
take softfp into account. Anyway, it seems it was useful long ago, but
it is no longer needed since option parsing has been improved:
-mfloat-abi is handled via arm.opt and updates the var_float_abi
variable. So, the last instance of -mfloat-abi= on the command line
wins.
This patch just removes this error message, thus enabling many more
tests to pass on arm-eabi:

gcc.target/arm/pr52375.c

Yeah, at the time it was added, the specs lines were used to directly
add preprocessor values and it was impossible at the time to deal with a
command-line where both variants were specified in terms of adding (or
not adding the correct defines). As you say, things have improved
significantly in that area and we can now eliminate this error.
I may have missed it, but do you have a similar patch for eliminating
the big/little endian error? That was added for the same basic reason,
but is now redundant as well.

No, because I didn't see any undesirable error related to that in
validation logs,
but sure I can prepare one.
