Fix the following static build failure raised since bump to version 1.15
in commit c31087182fa545784d9a0a01f0b32715d78c3955:

/home/buildroot/autobuild/instance-2/output-1/host/lib/gcc/arc-buildroot-linux-uclibc/12.2.0/../../../../arc-buildroot-linux-uclibc/bin/ld: /home/buildroot/autobuild/instance-2/output-1/host/lib/gcc/arc-buildroot-linux-uclibc/12.2.0/crtbeginT.o: relocation R_ARC_32_ME against `__TMC_END__' can not be used when making a shared object; recompile with -fPIC
