fpu_control.h is an installed header, and we generally want installed 
headers to be the same between different multilibs for the same compiler, 
so that a single include directory can be shared between multilibs.

Thus, it should not be in the fpu/ directory; instead, it should contain 
preprocessor conditionals to make most of the contents trivial in the 
soft-float case (as done for arm / m68k / mips / riscv / sh).
