pass user/maintainer provided CXXFLAGS to the Scintilla build process
* Usually, Scintilla will now be built with -O2
* this can improve performance significantly over the standard Scintilla -Os
(up to 10%).
* this also allows link-time-optimizing both Scintilla and SciTECO
(which are linked statically) by adding -flto to CFLAGS, CXXFLAGS and LDFLAGS.
Link-time-optimization will both reduce the total binary size
and improve performance slightly since scintilla_send_message() can be
inlined.
An -O3 optimized Scintilla when linked with LTO results in an only 300kb
larger SciTECO binary.
* the highest possible optimization thus requires the following maintainer
flags on the ./configure command line:
CFLAGS="-O3 -mtune=native -march=native -flto"
CXXFLAGS="-O3 -mtune=native -march=native -flto"
LDFLAGS="-flto"
* Windows and Debian builds use link-time-optimization now.
On Windows - where we link in everything statically - building
the dependant libraries with -flto could improve performance
even more.
* Debian builds respect the default hardening flags of the build
server now. This should ensure that SciTECO is built for the
correct architecture at the recommended optimization level etc.
