Obsoletes the powerpc-unknown-linux-gnuspe sample, so remove it.

     1 This patch sets the page size to a default 12, that is a 4KiB block size.

     2 Testing for the correct block-size is impossible when cross-compiling.

     4 It was build up by Yann E. MORIN <yann.morin.1998@anciens.enib.fr> from some

     5 bits gathered from buildroot, which is LGPL v2.1

     6 License for dmalloc is:

    18 I personnaly believe that the resulting code should therefore be

    19 LGPL v2.1, but don't believe me, ask your lawyers!
