[svn-r11420] Purpose:

Bug fix

Description:
Disabled C++ shared libraries for Sun Workshop compiler.

Solution:
This bug only seems to happen when using the -xarch=v9 flag to compile in
64-bit mode, but disabling shared libraries entirely for this compiler is
an easier fix (I don't know how to detect 64 bit mode from the command line).
The framework for disabling shared libraries for other C++ compilers is
in place.

Platforms tested:
sol, mir, sleipnir, modi4

+dnl Sun WorkShop C++ seems to have trouble with shared libraries in 64-bit
+dnl mode.  This may be related libtool's historical inability to handle the
+dnl -xarch=v9 flag, or the fact that our tests pass this flag as part of
+dnl the CXX variable rather than as a CXXFLAG.
+dnl Avoid the problem by turning off C++ shared libraries when this
+dnl compiler is involved.
