[Buildroot] [git commit branch/next] package/enlightenment: disable ptrace with xtensa and uClibc-ng

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=cce148558119047254981aab686deff16dbba1eb
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

uCLibc-ng needs to backport the uClibc commit
de6561f6669308e5d2297589b39a217d4c14df1c to add
PT_GETSIGINFO definition.

This commit is already merged in uClibc-snapshot used by
Buildroot's toolchains for xtensa.

For now, disable ptrace with xtensa uClibc-ng toolchains.

Thanks to Gergely Imreh for the initial investigation and
