Michael Nosthoff af148ef4f0 package/boost: fixup Optimization flag in boost build
When building with Boost Build the CXXFLAGS are extended depending
on the optimization level set. When not defined explicitly the
optimization level depends on the <variant>. For release it's 'speed'
and for debug it's set to 'off'

These flags overwrite the -O flag passed in with TARGET_CXXFLAGS as
it is appended when calling g++.

This commit sets the Optimization flags generated by Boost Build
to the value of TARGET_OPTIMIZATION no matter what level is used.

As Boost Build offers no nice way to alter those values the gcc
toolchain file is altered directly.

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
