[Bug libgcj/21935] New: All libjava execution tests fail on IRIX 6

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

All libjava execution tests fail on IRIX 6 like this:

% LD_LIBRARYN32_PATH=../../../gcc:../.libs ./PR9577
3709255:./PR9577: rld: Error: unresolvable symbol in ../.libs/libgcj.so.7: pthread_kill
3709255:./PR9577: rld: Error: unresolvable symbol in ../.libs/libgcj.so.7: pthread_sigmask
3709255:./PR9577: rld: Fatal Error: this executable has unresolvable symbols

Those two functions are only present in libpthread, but the IRIX 6
configuration still uses THREADS=single.

There seem to be two references to those function:

* pthread_kill used in java/lang/natPosixProcess.cc
  (java::lang::ConcreteProcess$ProcessManager::signalReaper)

* pthread_sigmask used in java/lang/natPosixProcess.cc
  (java::lang::ConcreteProcess$ProcessManager::waitForSignal)

Environment:
System: IRIX sculptor 6.5 10060437 IP32


	
host: mips-sgi-irix6.5
build: mips-sgi-irix6.5
target: mips-sgi-irix6.5
configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --with-gnu-as --with-as=/vol/gcc/lib/gas-2.15 --enable-libgcj --disable-multilib --with-gmp-dir=/vol/gnu/obj/gmp-4.1.3 --with-mpfr-dir=/vol/gnu/obj/gmp-4.1.3 --enable-languages=c,c++,f95,java,objc,ada --disable-libmudflap

How-To-Repeat:
Bootstrap as described above and run test libjava testsuite.
