User mode support for Linux ELF files with no section header

In user mode Linux, Qemu currently refuses to load ELF files that do not contain section headers (ehdr->e_shentsize == 0). Since section headers are not required in order to load an ELF file, simply removing the e_shentsize check in elf_check_ehdr() allows ELF binaries with no section headers to be run properly in user mode: Signed-off-by: Craig Heffner <[email protected]> Signed-off-by: Riku Voipio <[email protected]>
