Apparently all C++ compilations with
-m32 -march={i386,i486,i586,pentium,pentiumpro,lakemont,pentium4}
FAIL with:
<built-in>: warning: ‘--param constructive-interference-size=64’ is greater than ‘--param l1-cache-line-size=0’ [-Winterference-size]
So, either the C++ FE should not warn if param_l1_cache_line_size is 0
(treat it as a don't know value), or the backend shouldn't overwrite
the default generic param value of 32 with 0 when ix86_tune_cost->prefetch_block
is 0.

I'm also seeing this error during bootstrap on aarch64:
<built-in>: error: '--param constructive-interference-size=64' is greater than '--param l1-cache-line-size=32' [-Werror=interference-size]
