All sorts of new compiler flags seem to have been added in 1.6.10, probably need to compare to ours, figure out what they do and think about merging, along the lines of #442, initially it looks like this lot:

CXXFLAGS: -flto -w -x c++ -E -CC
CFLAGS: -std=gnu11 -flto -fno-fat-lto-objects

-E (preprocess only; do not compile, assemble or link)
-x c++ (specify language is c++)

no idea what -w (lowercase not upper) or -CC do

@sej7278
Added LTO flags etc. added in IDE 1.6.10 to provide smaller sizes and
4d32df7 
faster code (and apparently build times).

See issue sudar#446
