* stdio-common/stdio_lim.h.in: New file. All parameters
are adjustable at build time.
* Rules: Add a rule to build bits/stdio_lim.h from
stdio-common/stdio_lim.h.in. (It has to be in Rules so that
all subdirectories know how to make the file. It can't be
in Makerules because then it gets built at top level and the
dependencies are wrong.)

DT_RPATHs. This makes it effective again.

track of the memory map.
* elf/rtld.c (_dl_start): Initialise l_map_start for ld.so and
the executable.

modifier in asm, not c.
