ftp://mirrors.kernel.org appears to be down
This just uses the HTTP mirror instead, which isn't down.

Change a "inline" to "__inline__"
So "inline" isn't complient C, which means strict packages won't build
with it. This uses "__inline__" instead, which is ANSI C. This patch
is required to get freetype to build.

binutils: make objdump of branches more readable
Although we don't know the branch offsets until linker relaxation, we can
still fill in a tentative value to make objdumps of object code more
readable.

glibc: Undefine ELF_MACHINE_DEBUG_SETUP
Ensure that ld.so follows the preferred canonical behavior, whereby
dl_main() populates the DT_DEBUG entry in the .dynamic section with the
runtime address of the r_debug struct. GDB relies on r_debug to locate
the link map when reconstructing the shared library list.
This is documented in elf/rtld-debugger-interface.txt in the glibc
source tree.

glibc: work around libpthread static linking problem
This is a kludge, but statically linking against libpthread is useful,

Add an "--enable-linux" option to ./configure
I keep forgetting that the default option is to build newlib. This
flag changes the default target to Linux, so I don't keep forgetting
to type "make linux".

binutils: rework jump pseudoisntruction
"jump" was renamed to "tail" (as in tail call) and may freely clobber a
t-register, as before. A new "jump" was added that requires a second
argument, which is the scratch register it may clobber.
"tail" should be used for tail calls; "jump" should be used for
intraprocedural jumps more than 1 MiB away.

Use define_expand instead of define_insn_and_split for 64-bit
