package/strace: disable mpers support

Browse Source 
On aarch64 With the config option "--enable-mpers=check" the configure.ac
script searchs for a 32bit compiler. When a matching compiler is found
in the PATH some compatiblity checks are done. This can fail when the
available kernel headers on host and buildroot target does not match.

Since buildroot does not support 32bit binaries when building for 64bit
architecture (no -m32 option) we can disable this option unconditionally.

When disabling unconditionally also the configuration for toolchain using
MUSL can be removed.
