[PATCH 3/3] uclibc.inc: avoid immediate expansion for UCLIBC_EXTRA_CFLAGS

[Andre McCurdy <armccurdy@gmail.com>]

If immediate variable expansion is used, then UCLIBC_EXTRA_CFLAGS can
sometimes be derived from a partially expanded value of CFLAGS.

One specific problem case occurs when security_flags.inc is used: CFLAGS
is evaluated before the SECURITY_CFLAGS_pn-uclibc over-ride has been
applied and therefore UCLIBC_EXTRA_CFLAGS ends up being based on the
default SECURITY_CFLAGS instead of the uclibc specific value.
