A testcase for Linux/ia64
Working linker:
[...@gnu-14 kernel]$ ld -o gate-syms.o -T gate.lds gate.o
[...@gnu-14 kernel]$ ld -shared -s -soname=linux-gate.so.1 -o gate.so -T
gate.lds gate.o
[...@gnu-14 kernel]$ readelf -l gate.so
Elf file type is DYN (Shared object file)
Entry point 0xa000000000010640
There are 4 program headers, starting at offset 64
