sys-power/suspend-1.0 fails to compile with gcc-5
Probably the most simple fix is to add -std=gnu90 to the CFLAGS
The build fails in the linking phase with
undefined reference to `open_printk'
(and several other undefined references).
Which is clear, becaues there is
loglevel.h:inline void open_printk(void);
loglevel.c:inline void open_printk(void)
which is valid for C90, but for new C dialects, this will inline the function and not export it.

Fixed in suspend-1.0_p20150622.
