- If kallisti5 is having fun with RISC-V, why can't I too?
- Gets as far as complaining we don't have a libsolv package in
non-bootstrap builds

On most systems, "D" (deterministic) is now the default archiving mode,
and so specifying "u" will throw a warning that "D" is being used anyway.
Jam previously assumed, as it was passing "u", that the timestamps inside
.a's were valid when they were actually 0, which was leading to spurious
rebuilds of .as.
After this change, we assume archives cannot be scanned for timestamps,
which should stop the spurious rebuilds of targets on most systems.
Hopefully this is enough to satisfy the license requirements.
Remove some of the "LOCAL CHANGE" comments as a result (ones about
the HeaderCache remain.)
Moving it inside gcc dir allows gcc to detect and build isl while
building gcc. It has dependencies on other libraries that would
need to be prebuilt if we build it ourselves.
This is one of a few steps in building gcc with isl and allowing graphite
optimization flags.
Partially from @jarekpelczar's work, but only certain pieces that
were needed, and the rest is either from earlier GCC patches
or is my own work.
With this, GCC 7 can now build Haiku.
I had jam crash in strange ways because a stack-allocatted aray was
overflowing. Double the limit, and add sanity checks with exit and clear
error messages in case it happens again.
Flex is not needed, and creates some confusion when building the
binutils on Haiku. Just remove all the checks from the configure script,
so it is never used.
"* LINK_SPEC: Pass "-shared" to the linker only if it was passed to gcc; output
position-independent executables by default;" is reverted to workaround a
link failure on gcc4 with binutils 2.26: add-ons objects would fail to link
against an executable (being no more a shared object). This is possibly temporary
until the need for executable as shared objects is fully reviewed.
