+commit c2f7c5ad8ef0f9c94a2a8382c109c8c6e16c8b18

+ Fix realpath(name, NULL) when PSEUDO_DISABLED=1
+
+ On some Linux systems, dlsym("realpath", RTLD_NEXT) prefers
+ for reasons of its own to give a symbol that is also known
+ as old_realpath, which fails and yields EINVAL when called
+ with a null pointer as the second argument. This can be
+ avoided, on some systems, by using dlvsym() to request
+ the GLIBC_2.3 version of the symbol.
+
+ The wrapper logic is enhanced to allow for specifying
+ versions, although this currently only works for Linux
+ (Darwin has no dlvsym, apparently?). The test case is
+ a trivial program which calls realpath(name, NULL) run
+ with PSEUDO_DISABLED=1.
