Romain Naour 401c47e44b package/guile: dont't use -Os for CS 2014.05 ARM toolchain
With this toolchain, guile tigger an assembler error with -Os which is
probably caused by the binutils version being used:

arm-none-linux-gnueabi-ld --version
GNU ld (Sourcery CodeBench Lite 2014.05-29) 2.24.51.20140217

arm-none-linux-gnueabi-gcc --version
arm-none-linux-gnueabi-gcc (Sourcery CodeBench Lite 2014.05-29) 4.8.3 20140320 (prerelease)

Nowaday, even with a Buildroot internal toolchain using the oldest
Binutils GCC version (2.25.1 and 4.8.6), guile build fine with -Os.

So, force -O2 when this toolchain is used and BR2_OPTIMIZE_S is set.

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.
