/// Adapted from Linux kernel linker script failing due to out of range
/// relocation. The .vectors at 0xffff0000 is a common occurrence as the vector
/// table can only be placed at either 0 or 0xffff0000 in older ARM CPUs.
/// In the example the .vectors won't have an exception table so if LLD creates
/// one then we'll get a relocation out of range error. Check that we don't
/// synthesise a table entry or place a sentinel out of range.
/// Expect only .ARM.exidx from _start and sentinel
// CHECK: Hex dump of section '.ARM.exidx':
// CHECK-NEXT: 0x80000000 10000000 01000000 0c000000 01000000
