update the compilation config about redtamarin

[zwetan]

yes that mean in its actual state the source code will not build

[zwetan]

added new option build.MacOSXSDK = 109
this will force the build under Mac OS X
to use the Mac OS X SDK 10.9

the binaries generated will be compatible with

• Mac OS X 10.9
• Mac OS X 10.10
• Mac OS X 10.11

but they will fail with any version of Mac OS X lower than 10.9
eg. it will not work with Mac OS X 10.8 Mountain Lion or earlier
see Supported Operating System - Mac OS X

added new option build.makejobs = 3
Allow to set the number of make jobs that can run silmutaneously
setup by default to 3 (eg. 2 cores * 1.5 = 3)

if you have more cores you can increase this
number to speed up the build

for ex: on my Mac i7 with quad core I use
build.makejobs = 5

now all builds and build targets have been updated
to be in sync in what is documented in
Developer Environment

now the build will autodetect the python executable under Windows
because stupid Java does not understand 'python' under Cygwin
we need to use 'python2.7.exe'

the build is made in such a way that even if python version is updated
it should still work, eg with 'python.3.0.exe' etc.
