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.

     5     headers_install: fix __packed in exported kernel headers

     6     

     7     checkpatch.pl warns about using __attribute__((packed)) in kernel

     8     headers: "__packed is preferred over __attribute__((packed))". If one

     9     follows that advice it could cause problems in the exported header

    10     files, because the outside world doesn't know about this shortcut.

    11     

    12     For example busybox will fail to compile:

    13      CC      miscutils/ubi_attach_detach.o

    14      In file included from miscutils/ubi_attach_detach.c:27:0:

    15      /usr/include/mtd/ubi-user.h:330:3: error: conflicting types for ‘__packed’

    16      /usr/include/mtd/ubi-user.h:314:3: note: previous declaration of ‘__packed’ was here

    17     ...

    18     

    19     Fix the problem by substituting __packed with __attribute__((packed)) in

    20     the header_install.pl script.
