Include <fpu_control.h> only on glibc systems

​

The <fpu_control.h> header provides _FPU_*() macros, which the

Init_FPU() function uses only on i386, and only when they are

defined. Since <fpu_control.h> is not available, this causes a build

failure with C libraries such as musl. By simply including

<fpu_control.h> explicitly on glibc systems, we avoid the build

failure, since mpcenc.c already conditionally uses the <fpu_control.h>

macros only if they are defined.
