svn-r20475 added logic to rm <dlfcn.h> during build (in "Makefile.in") and remove its inclusion (in "include/link.h") when "not supporting" shared libraries. However the two conditionals are not the same: the first one tests "!HAVE_SHARED", while the second one tests "HAVE_NO_SHARED".
The problem is that "HAVE_NO_SHARED" is not always "!HAVE_SHARED" (AFAIK first one is auto-detected from ARCH, whereas second one is a user config choice if "!HAVE_NO_SHARED"). In this case:
- HAVE_NO_SHARED is not defined (ARCH supports shared libs),
- HAVE_SHARED is not defined (user doesn't want shared lib support),
<dlfcn.h> is rm'd by "Makefile.in", yet is still included by "include/link.h", which obviously doesn't compile.
(problem seen when using buildroot with uClibc-snapshot, during compilation of gcc's crtbegin*.o and crtend*.o -- I can provide more info (arch, versions, config, ...) if needed)
I'm not sure which one of the two conditions is the right one, but I'd go with "HAVE_NO_SHARED"? That's what the attached patch does, it fixed the problem in my case.
