$ cat makefile

$ make
gcc -c -maix64 a.c

ar: Creating an archive file libhello.a.
a - a.o
ar: 0707-126 a.o is not valid with the current object file mode.
        Use the -X option to specify the desired object mode.
<builtin>: 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

"-X mode Specifies the type of object file ar should examine. The mode must be one of the following:
Processes only 32-bit object files
Processes only 64-bit object files
Processes both 32-bit and 64-bit object files
Examines discontinued 64-bit XCOFF files (magic number == U803XTOCMAGIC).
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."
