[oe] [meta-oe] gpsd fails to compile due to scons-generated malformed command line

[Schäfer-Hutter]

FYI:

I had to patch the SConstruct file of gpsd like follows.

The first fix avoids double-quoting of the CPPFLAGS and the second
avoids calling ncurses5-config since that will end-up trying to link
the native x86-version of the ncurses library with cross-compiled
binaries.
