On 32-bit x86, _dl_find_object also returns a dlfo_eh_dbase address.
So far, compiling against a version of _dl_find_object which returns a
dlfo_eh_dbase was blocked using a #if + #error. This commit now
removes this compile time assertion and simply ignores the returned
dlfo_eh_dbase. All test cases are passing on a 32-bit build now.
According to https://www.gnu.org/software/libc/manual/html_node/Dynamic-Linker-Introspection.html,
dlfo_eh_dbase should be the base address for all DW_EH_PE_datarel
relocations. However, glibc/elf/dl-find_object.h says that eh_dbase
is the relocated DT_PLTGOT value. I don't understand how those two
statements fit together, but to fix 32-bit x86, ignoring dlfo_eh_dbase
seems to be good enough.
