Remove support for Solaris < 10 (PR gdb/22185)
Given that GCC has obsoleted/removed support for Solaris 9 in GCC 4.9/5 in 2013:
https://gcc.gnu.org/gcc-4.9/changes.html
https://gcc.gnu.org/ml/gcc-patches/2013-05/msg00728.html
and the last gdb version that can be compiled with gcc 4.9 is 7.12.1 only when
configured with --disable-build-with-cxx, it's time to obsolete/remove support
for Solaris < 10.
This patch does this, simplifying configure.nat along the way (only a single
sol2 configuration with variants for i386 and sparc).
Some configure checks for older Solaris versions can go, too, and the check
for libthread_db.so.1 removed:
* Since Solaris 10, dlopen has moved to libc and libdl.so is just a
filter on ld.so.1, so no need to check.
* $RDYNAMIC is already handled above (and is a no-op with Solaris ld
anyway).
Both proc-service.c and sol-thread.c lose support for (Solaris-only)
PROC_SERVICE_IS_OLD.
The attached revised patch has been tested on sparcv9-sun-solaris2.10,
sparcv9-sun-solaris2.11.4, amd64-pc-solaris2.10, amd64-pc-solaris2.11.4,
and x86_64-pc-linux-gnu.
I've also started an i386-pc-solaris2.9 build to check that it really
stops as expected.
