Hello,
Patch in the bottom adds support of IA MCU psABI to libgcc
(enables soft-fp) and libdecnumber (enables it for IA MCU).
Bootstrapped and regtested on top of [1/3] patch.
config/
* dfp.m4 (enable_decimal_float): Also set to yes for
i?86*-*-elfiamcu target.
gcc/
* configure: Regenerated.
libdecnumber/
* configure: Regenerated.
libgcc/
* config.host: Support i[34567]86-*-elfiamcu target.
* config/i386/32/t-iamcu: New file.
* configure: Regenerated.
Is it OK for trunk?

Thanks, K
