You could build the toolchain entirely with buildroot yes, and make
sure that you pass the new options when compiling the toolchain. As
far as I can see, BR2_TARGET_OPTIMIZATIONS is not respected when
building the toolchain itself. I think you need
BR2_EXTRA_GCC_CONFIG_OPTIONS for that.

An alternative is to use crosstool-ng to build the toolchain, but of
course you'll have to make sure that the options are passed there as
well.

Best regards,
Thomas
