[MIPS] Check info->executable to create DT_MIPS_RLD_MAP

Hi All,
When using "-pie", LD doesn't create the DT_MIPS_RLD_MAP entry,
because LD checks "!info->shared" and the "-pie" flag sets "info->shared" to true.
Note that LD checks "info->executable" to create DT_DEBUG, and
creating DT_MIPS_RLD_MAP should be similar to creating DT_DEBUG.
Ex:
/* SGI object has the equivalence of DT_DEBUG in the
DT_MIPS_RLD_MAP entry. This must come first because glibc
only fills in DT_MIPS_RLD_MAP (not DT_DEBUG) and some tools
may only look at the first one they see. */
if (!info->shared
&& !MIPS_ELF_ADD_DYNAMIC_ENTRY (info, DT_MIPS_RLD_MAP, 0))
return FALSE;
/* The DT_DEBUG entry may be filled in by the dynamic linker and
used by the debugger. */
if (info->executable
&& !SGI_COMPAT (output_bfd)
&& !MIPS_ELF_ADD_DYNAMIC_ENTRY (info, DT_DEBUG, 0))
return FALSE;
Any feedback about checking "info->executable" to create DT_MIPS_RLD_MAP and related stuffs?
Thanks a lot!
