# arch - The architecture to configure.
#
# NOTE: The i386 linker check for the option -exported_symbols_list fails
# because the autotool macro was written poorly so as to not account
# for cross-compiling. We know for a fact that Apple's toolchain supports
# -exported_symbols_list, so we force the result with:
#
# lt_cv_ld_exported_symbols_list=yes
#
# below.
#
# NOTE: iOS SDKs starting at 10 seem to have issues with clock_gettime,
# declaring the interface in time.h but not making the symbol
# available in libSystem.dylib, resulting in a runtime crash. For
# now, suppress use of clock_gettime on iOS by overriding
# configure and asserting:
#
# ac_cv_func_clock_gettime=no
# ac_cv_have_decl_clock_gettime=no
#
# below.
