branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
On SuperH, the BR2_PACKAGE_LIQUID_DSP_FAST option of the liquid-dsp
package causes triggers a compiler bug with the Sourcery CodeBench
toolchains:
src/filter/src/firdes.c:406:1: internal compiler error: in gen_reg_rtx, at emit-rtl.c:859
This commit works around this problem by simply making this option
unavailable with the problematic toolchains.
Fixes:
