RFR(L): 8161259: Simplify including platform files.

[Lindenmaier, Goetz]

Hi Andrew, 

unfortunately it's not that simple ... 
It does not grok the macro INCLUDE_SUFFIX_CPU, nor the dot in .hpp:

#define CONCAT4(a, b, c, d) a ## b ## c ## d
#define xcpu_header(x, y)    XSTR(CONCAT4(x, _, INCLUDE_SUFFIX_CPU, y))
#define cpu_header(basename)            xcpu_header(basename,.hpp)
cpu_header(globalDefinitions)

error: pasting "globalDefinitions_INCLUDE_SUFFIX_CPU" and "." does not give a valid preprocessing token

Best regards,
  Goetz
