stdbuf: support compilers other than __GNUC__
__SUNPRO_C >= 0x590 /*12.0*/ supports __attribute((constructor))
required by stdbuf, so use a more direct check for this.
Note ensure that --libexecdir is set to the appropriate
install location for libstdbuf.so so that stdbuf works
when installed on the system like it does when running
tests in the build directory.
* configure.ac (stdbuf_supported): Use a test prog to determine support.
* src/libstdbuf.c (stdbuf): Define appropriately for non GCC compilers,
and provide early feedback (compilation warning) if trying to compile
libstdbuf without the necessary support.
* src/stdbuf.c (set_LD_PRELOAD): Add a note on having stdbuf
look for libstdbuf.so in the default lib search path.
* cfg.mk (sc_prohibit-gl-attributes): Adjust so we can exclude
libstdbuf.so from prohibiting '__attribute', since we want
this form to avoid silently eliding this required attribute on non GCC.
Reported and tested by Rich Burridge.
