bdwgc is a garbage collector for C and C++. The Boehm-Demers-Weiser
conservative garbage collector can be used as a garbage collecting
replacement for C 'malloc' or C++ 'new'.
[Thomas:
- drop the dependency on host-bdwgc, since it is not needed. Only
host-guile will need host-bdwgc, but bdwgc itself doesn't need
host-bdwgc.
- add dependency on host-pkgconf, needed to detect libatomic_ops
- add --with-libatomic-ops=yes to force bdwgc to use the system
libatomic_ops, and not the internal one.
- instead of using BDWGC_LIBTOOL_PATCH = NO (needed to avoid patching
libtool because the libtool version used by bdwgc does not have a
corresponding patch in Buildroot), use BDWGC_AUTORECONF = YES,
which generates a proper libtool (without this, some -L/usr/lib
flags are added by libtool).]
