In static linking configurations, cups fails to build due to the lack of
Scrt1.o from uClibc toolchains. This Scrt1.o is only needed for PIE
binaries. Since we don't really care about PIE binaries in the context
of Buildroot, this commit solves the problem by patching cups to not
generate a PIE binary.

+Remove PIE flags from the build
+
+Generating a statically linked binary built with PIE requires the
+Scrt1.o file, which isn't part of Buildroot uClibc toolchains. To
+solve this, we simply disable the PIE flags.
