The LAPACK Testing and Timing Suites assume the use of the timing function ETIME.
On some IBM architectures such as IBM RS/6000s, the timing function ETIME is instead called ETIME_, and therefore the routines LAPACK/INSTALL/second.f and LAPACK/INSTALL/dsecnd.f should be modified.
On HPPA architectures, the compiler and loader flag +U77 should be included to access the function ETIME.
