be4ba40749 Make native gdb builds work.
* Makefile.in (relsrcdir): New.
(stamps/build-gcc-linux-stage1, stamps/build-gcc-linux-stage2)
(stamps/build-gcc-newlib-stage1, stamps/build-gcc-newlib/stage2): Pass
--src to configure set from relsrcdir.
This might be an actaul newlib bug: it's not providing a range error
when taking log1p of -1e80, but it appears that this triggered a glibc
bug from a while ago that may have not been fixed in newlib. I'm not
sure why the bug is just manifesting now (the newlib sources haven't
changed for a long time), but the glibc version has some macros that
force the evaluation of particular floating-point expressions (one of
which produces the range error) that don't exist in newlib.
I'm OK whitelisting the error for the next release, despite it
technically being a regression. log1p isn't a standard function, and I
doubt embedded users are going to notice. That said, we should still
fix it.
* Makefile.in (NEWLIB_NANO_TARGET_BOARDS): New.
(build-libc): Change build-newlib to stamps/build-newlib. Add
stamps/build-newlib-nano.

(build-gcc-newlib-stage2): Depend on merge-newlib-nano. Use
--with-sysroot instead of --with-headers. Also use
--with-native-system-header-dir.
(build-dejagnu): Install it.

(test/benchmarks/dhrystone/check): Add -specs= option. Use it in
$cc commands.
This has the same commits as the previous hash, it's just on the proper
branch now (so it's round-tripped through upstream's trunk). I archived
the old commit.
