Adhemerval Zanella 720480934a linux: Consolidate brk implementation 
It removes all the arch-specific assembly implementation.  The
outliers are alpha, where its kernel ABI explict return -ENOMEM
in case of failure; and i686, where it can't use
"call *%gs:SYSINFO_OFFSET" during statup in static PIE.

Also some ABIs exports an additional ___brk_addr symbol and to
handle it an internal HAVE_INTERNAL_BRK_ADDR_SYMBOL is added.

Checked on x86_64-linux-gnu, i686-linux-gnu, adn with builsd for
the affected ABIs.

README 

This hierarchy supports Linux systems using the new
asm-generic/unistd.h, which removes many familiar old syscalls.  For
example, to implement open(), newer Linux architectures require glibc
to invoke the __NR_openat syscall with AT_FDCWD.  This hierarchy
provides all those implementations.

It also provides support for 32-bit platforms using the 64-bit kernel
syscall APIs, as the 32-bit ones are no longer provided.  Note that
newer ILP32 environments (x32 or AArch64:ILP32, for example) are
converting to use more 64-bit types in kernel syscalls, so that aspect
of this support is in more flux as of this writing.
