build: Add support for TARGET_EXTRA_C{,PP}FLAGS

Add support for setting TARGET_EXTRA_C{,PP}FLAGS in board configs.
This can be used to set compiler flags for a board that break other
boards, such as -march=cortex-a9 or -DUSE_CUSTOM_EXTENSIONS_FOR_XYZ

definitions.mk: Don't fail if xmllint isn't installed

This is a workaround for xmllint currently not being installed on the
build slaves. It should be reverted when this is fixed, as it eliminates
a check for sane code.

build: Build fs_get_stats even for TINY_ANDROID

We need fs_get_stats if we're using u-boot because it's used
during tarball creation.
Build it even for TINY_ANDROID (unless TARGET_BOOTLOADER_TYPE == fastboot)
