   |  To use timercmp(), _BSD_SOURCE needs to be defined (if this manpage is to
   |  be believed: https://linux.die.net/man/3/timercmp). Can you try adding
   |  -D_BSD_SOURCE to HOST_CPPFLAGS in the fc-cache Makefile?
 
 That might work, but isn't the correct solution, anything built as part
 of the tools build needs to work using just standard functions (or macros)
 and timercmp() isn't (regardless how prevalent it might be), or functions
 defined in the tools compat header.
 
 I am about to commit a change which will simply define timercmp() in
 the relevant file if it isn't defined - there's nothing even vaguely
 system (or anything else) dependent about it.   That should fix it.
