Probe the compiler for the availability of the
__builtin_avr_delay_cycles() function, and modify the header files
<util/delay.h> and <avr/builtins.h> appropriately. Note that the
modification is done by setting __HAS_DELAY_CYCLES on top of those
files, which has been left overridable from the compiler
environment (i.e., commandline -D option) on purpose. Note also
that _delay_us() and _delay_ms() can only use
__builtin_avr_delay_cycles() if optimization is enabled as they'd
otherwise try to pass a floating-point argument to it which is not
allowed. (The compiler does not seem to be able to convert it
into an unsigned long internally, not even with a type cast.)
However, not enabling optimization for them yields garbage timing
anyway, due to moving the compile-time constant floating-point
calculations from the compiler into the AVR.
* configure.ac: Add detection of __builtin_avr_delay_cycles
* include/util/delay.h.in: repocopied from delay.h
