[v3] Fix ext/random/hypergeometric_distribution/operators/values.cc on Solaris 9

[Rainer Orth]

ext/random/hypergeometric_distribution/operators/values.cc fails to
compile on Solaris 9 which lacks full C99 support in libc/libm:

FAIL: ext/random/hypergeometric_distribution/operators/values.cc (test for excess errors)

WARNING: ext/random/hypergeometric_distribution/operators/values.cc compilation failed to produce executable


hypergeometric_pdf is defined in testsuite/util/testsuite_random.h
inside _GLIBCXX_USE_C99_MATH_TR1, but used unconditionally.  Fixed which
the following patch which allows the test to compile and pass on
i386-pc-solaris2.9.  On i386-pc-solaris2.11, it FAILs with an Arithmetic
exception, as it did before the patch:

Program received signal SIGFPE, Arithmetic exception.

__tmp is 0 here.

Ok for mainline?
