Fix stack size and address inconsistency due to executable stack
...
When a stack is marked executable due to loading a DSO that requires
an executable stack, the logic tends to leave out a portion of stack
after the first frame, thus causing a difference in the value returned
by pthread_getattr_np before and after the stack is marked
executable. It ought to be possible to fix this by marking the rest of
the stack as executable too, but in the interest of marking as less of
the stack as executable as possible, the path this fix takes is to
make pthread_getattr_np also look at the first frame as the underflow
end of the stack and compute size and stack top accordingly.
The above happens only for the main process stack. NPTL thread stacks
are not affected by this change.

Parse hexadecimal and octal strings correctly
...
The current implementation of __strtoul_internal seems to only pretend
to support hex and octal strings by detecting a preceding 0x or 0 and
marking base as 8 or 16. When it comes to the actual processing of the
string, it only considers numeric values within, thus breaking hex
values that may have [a-f] in them. Fixed with this commit.

New ld.so argument --inhibit-ldcache to disable ld.so.cache lookup
...
It may sometimes be desirable to make the dynamic linker only pick up
libraries from the library path and rpath and not look at the
ld.so.cache that ldconfig generates. An example of such a use case is
the glibc testsuite where the dynamic linker must not be influenced by
any external paths or caches.
This change adds a new option --inhibit-ldcache that when used, tells
the dynamic linker to not use ld.so.cache even if it is available.
