testsuite: Add a test case for PR110729 [PR110729]
As PR110729 reported, there was one issue for .section
__patchable_function_entries with -ffunction-sections, that
is we put the same symbol as link_to section symbol for all
functions wrongly. The commit r13-4294 for PR99889 has
fixed this with the corresponding label LPFE* which sits in
the function_section.
As Fangrui suggested [1], this patch is to add a bit more
test coverage. I didn't find a good way to check all
linked_to symbols are different, so I checked for LPFE[012].
