When generating XCOFF, the compiler generates a csect with an internal name.  Each function results in a lable within the csect.  This patch replaces the internal name ".text" with an empty string "".  This avoids adding special code to handle a function text() in the source file, and works better with some XCOFF tools that are confused when the csect and the first function have the same address.
