[Buildroot] missing reference to libm for MicroPerl

[Joshua Jackson]

I am currently running into an issue with the compilation of MicroPerl
fails with a missing libm reference. I found the following patch that
was date from a couple years ago:

This fixes builds on my system, but I'm not sure what else it might break.

Is there another fix / setting I might be missing to prevent the need
for this patch?

I am using a CentOS 6 x86_64 host and am compiling for a i586 x86_32 target.

Thanks,
Josh
