[help-gnuastro] Output file requires root

I have been trying out some programs (mainly astcosmiccal and asttable)
and they look very nice, thanks!

When installing the programs in a local folder everything works fine.
However, when installing in a system folder (./configure && make && make
check && make install):

$ astcosmiccal -z 1
/usr/bin/ld: cannot open output file
/usr/bin/.libs/9000-lt-astcosmiccal: Permission denied
collect2: error: ld returned 1 exit status

This would require to run gnuastro with root privileges. Is this
expected and is there a way to avoid it? Just out of curiosity, what is
the purpose of this .libs/ folder?

A couple of possible minor issues:
- section 9.1.3 (Invoking CosmicCalculator) of the book, it looks like
in the examples there should be no equal sign after short options, e.g.
  $ astcosmiccal --onlyvolume -z 0.8
- in gnuastro-0.2 the man page of asttable seems to be missing
