gnupg2: fix build on non-wchar toolchains

Browse Source 
The gnupg2 configure script checks whether <stdint.h> complies with
C99. When doing this, it expects a number of WCHAR_* definitions to be
present, which is not the case on non-wchar capable toolchains. The
gnupg2 configure script then concludes that <stdint.h> is not
C99-compliant and generates its own, which causes some build failures
related to intmax_t being not defined.

Since wchar is not actually used in gnupg2, this commit fixes this
problem by forcing gnupg2 to think that our <stdint.h> is
C99-compliant.

And lots of similar issues. Thanks a lot for Romain Naour for the
initial investigation and lots of discussion on IRC about this issue.
