Fix mips16 __fpu_control static linking (bug 18397).
Programs are supposed to be able to define the __fpu_control variable, overriding the library's version to cause the floating-point control word to be set to the chosen value at startup. This is broken for mips16 for static linking because the library's __fpu_control variable is in the same object file as the helper functions used by fpu_control.h for mips16, so test-fpucw-ieee-static fails to link with multiple definitions of __fpu_control. This patch fixes this by putting the helpers in a separate file rather than overriding fpu_control.c. Tested for mips16 that this fixes the link failure and the ABI tests still pass. [BZ #18397] * sysdeps/mips/mips32/fpu/fpu_control.c: Move to .... * sysdeps/mips/mips32/fpu/fpucw-helpers.c: ... here. Include <fpu_control.h> instead of <math/fpu_control.c>. * sysdeps/mips/mips32/fpu/Makefile: New file.
