[OE-core] [PATCH] valgrind: rrecommend libc6-dbg on all architectures

[Mike Crowe]

It seems that valgrind requires debug symbols to be available on all
architectures so there's no reason to treat arm and powerpc specially.

Ensuring that libc6-dbg is installed avoids errors like this on x86:

  valgrind:  Fatal error at startup: a function redirection
  valgrind:  which is mandatory for this platform-tool combination
  valgrind:  cannot be set up.  Details of the redirection are:
  valgrind:
  valgrind:  A must-be-redirected function
  valgrind:  whose name matches the pattern:      strlen
  valgrind:  in an object with soname matching:   ld-linux.so.2
  valgrind:  was not found whilst processing
  valgrind:  symbols from the object with soname: ld-linux.so.2
  valgrind:
  valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
  valgrind:  package on this machine.  (2, longer term): ask the packagers
  valgrind:  for your Linux distribution to please in future ship a non-
  valgrind:  stripped ld.so (or whatever the dynamic linker .so is called)
  valgrind:  that exports the above-named function using the standard
  valgrind:  calling conventions for this platform.  The package you need
  valgrind:  to install for fix (1) is called
  valgrind:
  valgrind:    On Debian, Ubuntu:                 libc6-dbg
  valgrind:    On SuSE, openSuSE, Fedora, RHEL:   glibc-debuginfo
  valgrind:
  valgrind:  Cannot continue -- exiting now.  Sorry.
