[PATCH][libstdc++-v3] Add _GLIBCXX_HAVE_LIMIT_FSIZE to guard 27_io/fpos/14775.cc

[Renlin Li]

Hi all,

This is a simple patch to add _GLIBCXX_HAVE_LIMIT_FSIZE to guard the test.
In libstdc++-v3/testsuite/util/testsuite_hooks.cc. set_file_limit() 
function is nullified when either _GLIBCXX_RES_LIMITS or 
_GLIBCXX_HAVE_LIMIT_FSIZE is not defined.
_GLIBCXX_USE_LFS can cover _GLIBCXX_RES_LIMITS, however, 
_GLIBCXX_HAVE_LIMIT_FSIZE is not checked.

The complete condition for correct execution of this test case is that, 
those two macros are both defined.

Is Okay to commit?

Regards,
Renlin Li
