i686-linux-gnu-no-pie build failure

[Joseph Myers]

With GCC mainline, we have a failure

FAIL: glibcs-i686-linux-gnu-no-pie build

that appears to result from the GCC change:

    x86-64: Add --enable-x86-64-mfentry

This warning "'-pg' without '-mfentry' may be unreliable with shrink 
wrapping" doesn't have an option to control it.  I suppose we need to 
change options used to build profiling glibc for i686 to avoid this 
warning?
