libstdc++: Disable -Wlong-long warnings in boost_concept_check.h

The _IntegerConcept, _SignedIntegerConcept and _UnsignedIntegerConcept
class template are specialized for long long, which gives warnings with
-Wsystem-headers in C++98 mode.

libstdc++-v3/ChangeLog:

	* include/bits/boost_concept_check.h: Disable -Wlong-long
	warnings.
	* testsuite/24_iterators/operations/prev_neg.cc: Adjust dg-error
	line number.
