[PATCH] PowerPC libm-test.inc expl(1000.0L) result exceeds __LDBL_MAX__ for IBM Long Double 128.

[Ryan S. Arnold]

The result of the libm-test.inc test_expl() function's expl(1000.0L)
test exceeds the value of __LDBL_MAX__ for IBM Long Double 128.

GCC 4.3 is more pedantic than GCC 4.1 and throws out a warning as an
error when storing the constant return value causing a make check
failure.  The same warning as an error is generated with GCC 4.1 when it
is compiled with the -pedantic flag.

The following test should be excluded on PowerPC to prevent make check
failures.

TEST_f_f (exp, 1000.0L, 0.197007111401704699388887935224332313e435L);

The following patch excludes it on PowerPC by testing against
__LDBL_MAX_EXP__ since one can't test against floating point values in
pre-processor directives.
