This architecture variant is broken in GCC, causing build failures:
../../../libgcc/config/arm/unwind-arm.c:467:1: error: unrecognizable insn:
467 | }
| ^
(insn 2 4 3 2 (set (reg/v/f:SI 118 [ p ])
(reg:SI 0 r0 [ p ])) "../../../libgcc/config/arm/unwind-arm.c":456:1 -1
(nil))
during RTL pass: vregs
../../../libgcc/config/arm/unwind-arm.c:467:1: internal compiler error: in extract_insn, at recog.c:2770
Reported to the GCC developers, the feedback was "iwmmxt support is
definitely bitrotten and most likely should be removed from GCC.".
See:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106972#c1
So this commit simply drops support for iwmmxt, which anyway is
probably barely used nowadays: it's for old Marvell PXA cores that
implemented a special SIMD instruction set. The BR2_xscale option can
be used instead, it's just that it won't use this SIMD instruction
set.
