Make two libstdc++ tests use -Wl,--no-enum-size-warning for ARM Linux EABI

[Joseph S. Myers]

Various g++ and gfortran tests use -Wl,--no-enum-size-warning for
arm*-*-linux*eabi to avoid linker warnings when the test using
-fshort-enums is linked against libraries not using -fshort-enums.
Two libstdc++ tests need to use this option as well.  This patch adds
the option to them; OK to commit?

	testsuite/20_util/make_unsigned/requirements/typedefs-2.cc: Use
	-Wl,--no-enum-size-warning for arm*-*-linux*eabi.
