Processing GNU-style "make variables" - implementation
Support the following "make variables":
AR (GNU compatible)
ARFLAGS (GNU Compatible)
AS (GNU Compatible)
ASFLAGS (GNU Compatible)
CC (GNU Compatible)
CFLAGS (GNU Compatible)
CXX (GNU Compatible)
CXXFLAGS (GNU Compatible)
CPP (GNU Compatible)
CPPFLAGS (GNU Compatible)
CPPDEFINES List of CPP macro definitions. Alternative for -D
CPPINCLUDES List of CPP inclusion directories. Alternative for -I
HASHBANGPERL Perl invocation to be inserted after '#!' in public
perl scripts.
LDFLAGS (GNU Compatible)
LDLIBS (GNU Compatible)
RANLIB Program to generate library archive index
RC Program to manipulate Windows resources
RCFLAGS Flags for $(RC)
RM (GNU Compatible)
Setting one of these overrides the corresponding data from our config
targets. However, flags given directly on the configuration command
line are additional, and are therefore added to the flags coming from
one of the variables above or the config target.
Fixes #2420
