>Description:
	_rtld_digest_phdr() in headers.c asserts that there are exactly
	2 PT_LOAD sections in the shared object.  This is not always true.

>How-To-Repeat:
	Code inspection.  Or lose badly with a shared object with
	other than 2 PT_LOAD sections.

 revision 1.62
 date: 2017-06-23 18:29:21 +0300;  author: joerg;  state: Exp;  lines: +11 -12;  commitid: 9duF2Q9DPoICLvWz;
 branches:  1.62.4;
 Remove old assert that only two segments exist. The rest of the code has
 been changed to cope with more and at least Go actively creates them.
 Adjust the mapping size computation to use the maximum and not depend on
 PT_LOAD segments to be in order.

State-Changed-Why:
There is still this limitation in _rtld_map_object which makes ldd complain
about such objects.
