[PATCH 2/2] arm/ts-sp-common: Workaround unused-but-set-variable errors

With the new GCC, we're seeing the following error:
| In file included from /builder/meta-arm/build/tmp/work/armv8-5a-poky-li=
nux/ts-sp-smm-gateway/git/sources/ts/components/common/dlmalloc/malloc_wr=
apper.c:62:

ent':

|  4002 |   int nfences =3D 0;
|       |       ^~~~~~~

To workaround this issue, add "-Wno-error=3Dunused-but-set-variable" to T=
ARGET_CFLAGS
