Assertion fail at peicode.h:607

This is the assertion that vars->string_ptr < vars->end_string_ptr,
ie. when it fails we've overflowed the string buffer area.  Caused by
allocating space for import_name but writing symbol_name, and they can
be different.

	* peicode.h (SIZEOF_ILF_STRINGS): Revert 042f14505e change.
