MFC 275412:
The runtime linker needs to include a path to itself in the link map it exports to the debugger. It currently has two choices: it can use a compiled-in path (/libexec/ld-elf.so.1) or it can use the path stored in the interpreter path in the binary being executed. The runtime linker currently prefers the second. However, this is usually wrong for compat32 binaries since the binary specifies the path of rtld on a 32-bit system (/libexec/ld-elf.so.1) instead of the actual path (/libexec/ld-elf32.so.1). For now, always assume the compiled in path (/libexec/ld-elf32.so.1) as the rtld path and ignore the path in the binary for the 32-bit runtime linker.
