Installation script not working on newer Raspberry pi(s) (+fix)

[chtronche]

This boils down to the platform detection being made with
grep -q BCM2708 /proc/cpuinfo
(approx line 300 in the script), while newer RPIs report BCM2709, hence it may be fixed by changing to grep -q BCM270[89]

It recognizes my RPi2 but somehow can't download the PHP binary.

It looks like wget (GNU Wget 1.16.3 built on linux-gnueabihf) doesn't like the bintray URL and fails to download the binaries. By removing wget it worked (need curl installer).
