[Buildroot] [PATCH 1/1] package/dmalloc: needs -fPIC

Drop first patch and pass -fPIC to configure to fix the following build
failure on ARC:

ERROR: architecture for "/usr/lib/libdmalloc.so" is "ARCompact", should be "ARCv2"
ERROR: architecture for "/usr/lib/libdmallocth.so" is "ARCompact", should be "ARCv2"
ERROR: architecture for "/usr/lib/libdmallocthcxx.so" is "ARCompact", should be "ARCv2"
ERROR: architecture for "/usr/lib/libdmallocxx.so" is "ARCompact", should be "ARCv2"

This build failure is due to the following configure error:

checking shared library link args... ./configure: line 4467: 10229 Segmentation fault      ( ${LD-ld} -shared --whole-archive -soname conftest.so -o conftest.so.t conftest.a ) 2>&5
/home/buildroot/autobuild/run/instance-0/output-1/host/bin/arc-buildroot-linux-gnu-ld -G -o $@.t

This configure error is due to missing -fPIC:
