IA MCU psABI support: changes to libraries
Patch in the bottom adds support of IA MCU psABI to libgcc (enables
soft-fp) and libdecnumber (enables it for IA MCU).
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/t-softfp-sfdftf: New file.
* config/i386/32/t-iamcu: Likewise.
* configure: Regenerated.
