I wanted to check whether libatomic-ops.a gets built with -fPIC so I
tried to build it:

$ ./autogen.sh
automake: configure.in: installing `./install-sh'
automake: configure.in: installing `./mkinstalldirs'
automake: configure.in: installing `./missing'
src/Makefile.am:7: NEED_ASM does not appear in AM_CONDITIONAL
src/atomic_ops/sysdeps/Makefile.am:2: invalid variable `nobase_sysdep_HEADERS'
doc/Makefile.am:3: invalid variable `dist_pkgdata_DATA'
$ ./configure
  [...snip...]
$ make
  [...snip...]
gcc -DHAVE_CONFIG_H -I. -I. -I.    @PICFLAG@ -g -O2 -c atomic_ops_stack.c
gcc: @PICFLAG@: No such file or directory
  [...snip...]

Looks like @PICFLAG@ needs to be substituted by configure?
