# runs.
#
# it's purpose is to call __libc_init with appropriate
# arguments, which are:
#
# - the address of the raw data block setup by the Linux
# kernel ELF loader
#
# - address of an "onexit" function, not used on any
# platform supported by Bionic
#
# - address of the "main" function of the program.
#
# - address of the constructor list
