gdb/testsuite: new test for recent dwarf reader issue
A new test (gdb.base/signed-builtin-types.exp) was added that made use
of 'info sources' to figure out if the debug information for a
particular object file had been fully expanded or not. Unfortunately
some lines of the 'info sources' output can be very long, this was
observed on some systems where the debug information for the
dynamic-linker was installed, in this case, the list of source files
associated with the dynamic linker was so long it would cause expect's
internal buffer to overflow.
This commit switches from using 'info sources' to 'maint print
objfile', the output from the latter command is more compact, but
also, can be restricted to a single named object file.
With this change in place I am no longer seeing buffer overflow errors
from expect when running gdb.base/signed-builtin-types.exp.

sim: or1k: move arch-specific settings to internal header
There's no need for these settings to be in sim-main.h which is shared
with common/ sim code, so move it all out to the existing or1k-sim.h.
Unfortunately, we can't yet drop the or1k-sim.h include from sim-main.h
as many of the generated CGEN files refer only to sim-main.h. We'll
have to improve the CGEN interface before we can make more progress,
but this is at least a minor improvement.

libsframe: fix a memory leak in sframe_decode
sframe_decode () needs to malloc a temporary buffer of the same size as
the input buffer (containing the SFrame section bytes) when endian
flipping is needed. The decoder keeps the endian flipped contents in
this buffer for its usage. This code is necessary when the target
endianneess is not the same as host endianness.
The malloc'd buffer needs to be kept track of, so that it can freed up in
sframe_decoder_free () later.
ChangeLog:
* libsframe/sframe-impl.h (struct sframe_decoder_ctx): Add new
member to keep track of the internally malloc'd buffer.
* libsframe/sframe.c (sframe_decoder_free): Free it up.
(sframe_decode): Update the reference to the buffer.

gdb/testsuite: remove MPFR detection in gdb.base/float128.exp
I see this fail since commit
991180627851 ("Use toplevel configure for
GMP and MPFR for gdb"):
FAIL: gdb.base/float128.exp: show configuration
The test fails to find --with-mpfr or --without-mpfr in the "show
configuration" output. Since MPFR has become mandatory, we can just
remove that check and simplify the test to assume MPFR support is there.
