Fixed issue for compiling mysql plugin on Solaris

On Solaris, in the case where the mysql libraries were compiled using a
non-gcc compiler, but the plugins are being compiled with gcc, the configure
process would incorrectly determine the MYSQLCFLAGS. This has been corrected
in the m4/np_mysqlclient.m4 file.
