[Buildroot] [git commit] pdbg: bump version to latest

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=fe7285cd4e985a82d846302ef6ed8053c4e9a26d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

I got this error when attempting to build:

 aclocal: error: couldn't open directory 'm4': No such file or directory

So we now have the post patch hook to ensure the m4 directory is
present.

In addition, the package now sets a variable with the Git SHA1 so that
the binary contains the expected output for --version.

Specific configurations of uClibc cause a build failure in pdbg. This commit
adds a patch to remove the definition of the offending macro (it is unused in
the source).

 include/bits/uClibc_stdio.h:149:16: error: expected identifier or ???(??? before ???;??? token
   void *__unused;    /* Placeholder for codeset binding. */

+Subject: [PATCH] libpdbg: Remove unused __unused from compiler.h
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The compiler.h header contains a macro that defines __unused. When
+building against uClibc this collides with uClibc_stdio.h:
+
+In file included from /usr/include/stdio.h:71:0,
+                 from libpdbg/fake.c:17:
+/usr/include/bits/uClibc_stdio.h:149:16: error: expected identifier or ???(??? before ???;??? token
+  void *__unused;    /* Placeholder for codeset binding. */
+                ^
+
+As it is unused in pdbg, remove it.
