reset upstream subtrees to yocto 2.6

Reset the following subtrees on thud HEAD:

  poky: 87e3a9739d

+Subject: [PATCH] symbol: Account for prelinked shared objects
+
+Some projects, such as those derived from Yocto, tend to prelink their
+binaries and libraries to reduce runtime overhead. Currently this trips
+up pyflame in its symbol address calculations, and leads to ptrace
+failures due to spurious addresses:
+
+   $ pyflame -t python -c "print 'foo'"
+   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
+   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
+   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
+   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
+   Unexpected ptrace(2) exception: Failed to PTRACE_PEEKDATA (pid 1482, addr 0x9f9b1d70): Input/output error
+   ...
+
+Add support for reading a prelinked base p_vaddr out of the ELF and
+adjust the PyAddresses values accordingly.
