[PATCH v2 1/1] eglibc: always compile with optimization.

[jackie.huang]

From: Jackie Huang <jackie.huang@windriver.com>

eglibc fails to compile if someone tries to compile an entire image as -O0:
error "glibc cannot be compiled without optimization"
so in this case, force to use -O2 and give a note about it.

[YOCTO #3405]
