comptools: do not force build of make-3.81 unless really needed
On systems with make-3.82, we forcibly force the build and the use
of make-3.81
But some newer tools break when building with make-3.81. For example,
eglibc-3.18 breaks.
Introduce a new blind options that tools may select if they require
make-3.81. If the system does not have make-3.81, and this option is
selected, then we force the build of make-3.81. Otherwise, we leave
it to the user to decide on his own.
Note that no component selects this option for now. It will come in
later patches as we find them.

fnstsw stores 16bit into %ax. The upper 16bit of %eax is unchanged.

The new assembler (binutils-2.18.50.0.4 and up) will disallow "fnstsw %eax".
