All right. Thank you.

In BSD system, '/usr/obj' + <current directory> is used for build directory.
(from now on, I say it 'obj' directory.)
% cd /home/owner/prog
% make obj <= make 'obj' directory
/usr/obj/home/owner/prog created for /home/owner/prog
% make
cc -O -pipe -Wall -I/home/owner/prog -c /home/owner/prog/main.c
...
% ls *.o
ls: No match. <= source directory is read only.
% cd /usr/obj/home/owner/prog
% ls *.o
main.o ... <= *.o files are wrtten in 'obj' directory.
...
To support BSD build system, global locate tag files not only in source
directory but also in 'obj' directory.
% cd /home/owner/prog
% make obj <= make 'obj' directory
% gtags /usr/obj/home/owner/prog <= write tag files in 'obj'
% ls G* directory.
ls: No match.
% global -x main
main 83 main.c main(argc, argv)
% cd /usr/obj/home/owner/prog
% ls G*
GPATH GRTAGS GSYMS GTAGS
If there is a convention in automake, I can support it.
