POSIX shells treat an unquoted [abcd] as a pattern bracket expression
and apply it for filename expansion. This kicks in and causes
troubles in the space_pad_to function when it's called to pad prefix
tags like '[AUTODETECT]', because the argument holding such a tag is
passed to a shell unquoted. The result is funny output when the
directory containing the Makefile also contains any files or
directories, whose name is a single upper-case character that can be
found in any prefix tags:
$ touch A B C D
$ make

Prevent this by quoting space_pad_to's parameter when passing it to a
shell.
doesn't support LTO or plugins. Fixes Issue #456
So essentially LTO support will only be enabled with avr-gcc 4.9.2 which comes with 1.6.10 or later
and Debian, Ubuntu etc; not 4.8.1 which comes with IDE 1.6.9 and a few earlier versions.
Tested with:
* 1.6.8 (avr-gcc 4.8.1 which doesn't support LTO so uses avr-ar and doesn't set LTO flags)
* 1.6.12 (avr-gcc 4.9.2 which supports LTO so uses avr-gcc-ar and sets LTO flags)
* 1.0.5 with Debian avr-gcc 4.9.2 (supports LTO so uses avr-gcc-ar and sets LTO flags)
$ARCHITECTURE is probably safe as that's usually called $ARCH.
Fixes issue #386.
Need to decide if this is going to upset too many user's who have already
started using $VENDOR - and who uses tcsh? ;-)
With this fix the `TARGET` variable is set correctly when the project directory
(or its path) contains spaces. So in this case:
/Users/Joe/Dropbox (Personal)/example project
`TARGET` will be set to `example_project` instead of `Dropbox example project`
(like it was before this fix).
Needed to fix the new wiring_pulse.S in IDE 1.6.5 which
also has a wiring_pulse.c source file.
Mostly rebased @peplin's PR #266, so should allow us
to support newer chipKIT builds too.
I found that the previous reset code did not work for Leonardo or Micro, nor did any reset code anywhere on the internet.
An examination of the Arduino IDE source code (and the JNI code behind its serial implementation) shows that it holds RTS high and DTR low when doing the 1200 baud open/close. And it turns out that's exactly what's needed!
