ar: 0707-126 a.o is not valid with the current object file mode.
Use the -X option to specify the desired object mode.
: recipe for target 'libhello.a(a.o)' failed
make: *** [libhello.a(a.o)] Error 1
rm a.o
$

Aix ar requires an option to specify the object file format.

Quote from
https://www.ibm.com/support/knowledgecenter/ssw_aix_72/a_commands/ar.html


"-X modeSpecifies the type of object file ar should examine. The mode 
must be
one of the following:
32
Processes only 32-bit object files
64
Processes only 64-bit object files
32_64
Processes both 32-bit and 64-bit object files
d64
Examines discontinued 64-bit XCOFF files (magic number == U803XTOCMAGIC).
any
Processes all of the supported object files.
The default is to process 32-bit object files (ignore 64-bit objects). The
mode can also be set with the OBJECT_MODE environment variable. For example,
OBJECT_MODE=64 causes ar to process any 64-bit objects and ignore 32-bit
objects. The -X flag overrides the OBJECT_MODE variable."

Details:

GNU Make has a segmentation fault regression in make 4.3, where the exact same
make code works fine with make 4.2.1.

The stack trace looks like this:

Program received signal SIGSEGV, Segmentation fault.

To reproduce:

$ git clone https://github.com/buildroot/buildroot.git
$ cd buildroot
$ make BR2_HAVE_DOT_CONFIG=y -s printvars VARS=%_LICENSE

Works with make 4.2.1 (and produces the expected output), segfaults with make
4.3 (with the above stack trace captured using gdb).
