This solves it for fedora:29,
arc_gnu_2017.09-rc2_prebuilt_uclibc_le_arc700_linux_install,
arc_gnu_2019.03-rc1_prebuilt_uclibc_le_archs_linux_install and
arc_gnu_2019.03-rc1_prebuilt_glibc_le_archs_linux_install.
Also ok with:
make -C tools/perf build-test
Now build testing with the full set of containers.

perf tools: Remove needless asm/unistd.h include fixing build in some places
We were including sys/syscall.h and asm/unistd.h, since sys/syscall.h
includes asm/unistd.h, sometimes this leads to the redefinition of
defines, breaking the build.
Noticed on ARC with uCLibc.
