The soft-float targeted toolchains have switched to -mfloat-abi=soft from -mfloat-abi=softfp.
{% endcall %}

{% call format("newscont") -%}
This makes arm-linux-gnueabi and armeb-linux-gnueabi toolchains use "soft" FP ABI instead of "softfp".
{% endcall %}

{% call format("newscont") -%}
Historically, TCWG's toolchains provided both "soft" and "softfp" multilibs, but when switching from crosstool-ng to cbuildv2/abe (which support a single multilib) "softfp" multilib was choosen.  Using "-mfloat-abi=soft" is a better choice for a gnueabi toolchain, since it doesn't require cores to have a floating-point unit.
{% endcall %}

{% call format("newscont") -%}
This change should not break compatibility for toolchain users since the ABI will stay the same.  The compiler and glibc libraries will not refernce FP instructions.
