+Subject: [PATCH] CMakeLists.txt: compile squirrel with -fPIC
+
+Ensure that squirrel is compiled with -fPIC to allow linking the static
+libraries with dynamically linked programs. This is not a requirement
+for most architectures but is mandatory for ARM.
+
+Fixes:
+x86_64-buildroot-linux-musl/bin/ld: CMakeFiles/sq_static.dir/sq.c.o: relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a PIE object; recompile with -fPIC
+x86_64-buildroot-linux-musl/bin/ld: final link failed: nonrepresentable section on output
