libgtk3: remove non-existent configure options

1 gc/configure.ac: add check for NO_GETCONTEXT definition
3 This patch is ported from bdwgc package. Since Gauche uses an internal
4 copy of the boehm gc code, it is affected by the same problem.
6 Both configure and configure.ac are modified because autoreconf fails
7 due to an incompatibility with the version of the autotools used by
8 Buildroot.

15 AS_IF, remove debug traces, use AC_CHECK_FUNCS (as suggested by
16 Thomas)]
