On AIX 7.2, for a 64-bit build, the environment variable AR needs to be set
to 'ar -X 64', see
https://gitlab.com/ghwiki/gnow-how/-/wikis/Platforms/Configuration .
This is what I have done, and nevertheless the groff build fails:
$ make
...
GEN src/utils/lookbib/lookbib.1
make all-am
AR libdriver.a
ar: 0707-126 src/libs/libdriver/input.o is not valid with the current object
file mode.
Use the -X option to specify the desired object mode.
ar: 0707-126 src/libs/libdriver/printer.o is not valid with the current object
file mode.
Use the -X option to specify the desired object mode.
make: 1254-004 The error code from the last command is 2.
Passing V=1 to see the details:
$ make V=1
make all-am
rm -f libdriver.a
ar cr libdriver.a src/libs/libdriver/input.o
src/libs/libdriver/printer.o
ar: 0707-126 src/libs/libdriver/input.o is not valid with the current object
file mode.
Use the -X option to specify the desired object mode.
ar: 0707-126 src/libs/libdriver/printer.o is not valid with the current object
file mode.
Use the -X option to specify the desired object mode.
make: 1254-004 The error code from the last command is 2.
This is caused by the line in Makefile.am:
AR=ar
config.status contains the correct value:
S["AR"]="ar -X 64"
The attached patch will fix it.

Subject: [PATCH] build: Fix build failure on AIX in 64-bit mode.
* Makefile.am (AR): Remove hardcoded value. Let Automake use the value from
config.status.
