Fix integer overflow in very long sections in ELF objects
The source is an ElfXX_Off, which is an unsigned 32- or 64-bit. That means any section bigger than 2 GB would cause an overflow when we assigned in m_stringTableFileOffset = strtab.offset; Change-Id: Ib47c56818178458a88b4fffd15546bd47a89894e Fixes: QTBUG-70560 Reviewed-by: Olivier Goffart (Woboq GmbH) <> (cherry picked from commit cb5c24fa26142edaff8fd2c9787dbe45c222b4ff) Reviewed-by: Jędrzej Nowacki <> (cherry picked from commit 9f95f25d2ef3de76d449bc4de5b09e87e9ed537a)
