[PATCH v2] tune-cortexa32: Fix libgcc-initial build issue for cortex-a32

[Jagadeesh Krishnanjanappa]

When we try to build images for machine which is tuned for
cortex-a32, then libgcc-initial recipe fails to build with
below error message.

- Replacing TUNE_FEATURES from aarch64 to armv8a will solve the above
build issue.
- Changed BASE_LIB to 'lib', as cortex-a32 is a 32bit ARMv8a architecture.

The sample machine config file (qemuarma32.conf) used to reproduce
the error looks like:

-- snip --

require conf/machine/include/tune-cortexa32.inc
require conf/machine/include/qemu.inc

KERNEL_IMAGETYPE = "Image"

SERIAL_CONSOLES ?= "115200;ttyAMA0 115200;hvc0"

KMACHINE_qemuarma32 = "qemuarm64"
