ar: 0707-126 a.o is not valid with the current object file mode.
Use the -X option to specify the desired object mode.

"-X mode Specifies 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."
