arch: um: Fix build for statically linked UML w/ constructors
If CONFIG_CONSTUCTORS is enabled on a statically linked
(CONFIG_STATIC_LINK=y) build of UML, the build fails due to the
.eh_frame section being both used and discarded:
ERROR:root:`.eh_frame' referenced in section `.text' of /usr/lib/gcc/x86_64-linux-gnu/11/crtbeginT.o: defined in discarded section `.eh_frame' of /usr/lib/gcc/x86_64-linux-gnu/11/crtbeginT.o
`.eh_frame' referenced in section `.text' of /usr/lib/gcc/x86_64-linux-gnu/11/crtbeginT.o: defined in discarded section `.eh_frame' of /usr/lib/gcc/x86_64-linux-gnu/11/crtbeginT.o
Instead, keep the .eh_frame section, as we do in dyn.lds.S for
dynamically linked UML.
This can be reproduced with:
./tools/testing/kunit/kunit.py run --kconfig_add CONFIG_STATIC_LINK=y --kconfig_add CONFIG_GCOV_KERNEL=y --kconfig_add CONFIG_DEBUG_FS=y
