# Define the libc run-time (crt) support object files that must be built,
# which are needed to build all other objects (shared/static libs and
# executables)
# ==========================================================================
# AArch64, ARM, MIPS, and x86 all need crtbegin_so/crtend_so.
#
# For x86, the .init section must point to a function that calls all
# entries in the .ctors section. (on ARM this is done through the
# .init_array section instead).
#
# For all the platforms, the .fini_array section must point to a function
# that will call __cxa_finalize(&__dso_handle) in order to ensure that
# static C++ destructors are properly called on dlclose().
#
# Args:
# my_2nd_arch_prefix: set to $(TARGET_2ND_ARCH_VAR_PREFIX) if it's
# for the 2nd arch; otherwise empty.
