We run Intel MCU psABI tests on Linux/ia32 with -miamcu. Since Intel
MCU psABI has a different calling convention, the only Linux libc function
allowed is "abort".
asm-support.S contains some support functions as well as a subset of
soft-fp, which is written in assembly with x87 instructions, to provide
intrinsics needed by -miamcu so that Intel MCU psABI tests can run on
Linux.
