wolfssl: use -fomit-frame-pointer to fix asm error

32-bit x86 fail to compile fast-math feature when compiled with frame
pointer, which uses a register used in a couple of inline asm functions.

Previous versions of wolfssl had this by default.  Keeping an extra
register available may increase performance, so it's being restored for
all architectures.
