for non-multilib configurations.

# NB: Modifying both CT_TARGET_CFLAGS and CT_ALL_TARGET_CFLAGS: the __ANDROID_API__
# definition needs to be passed into GCC build, or the resulting libstdc++ gets
# miscompiled (attempt to link against it results in unresolved symbols to stdout/...).
# And since __ANDROID_API__ is a user config option, placing it with other user-supplied
# options isn't completely out of character.
# On the other hand, CT_ALL_TARGET_CFLAGS in non-multilib builds is already set and does
# not get recalculated after GCC build, so setting CT_TARGET_CFLAGS is not reflected
# on other libraries/apps, such as gdbserver.
