[Buildroot] [PATCH 1/1] package/quota: fix build on m68k

[Fabrice Fontaine]

PIE breaks the build on m68k, so add an upstream patch to disable PIE.
Obviously, when we start seriously testing the BR2_RELRO_FULL option, we
will realize that it is broken on some architectures, and will probably
disable it on m68k.

Fixes:

+Subject: [PATCH] configure.ac: add --disable-pie option
+
+PIE is not necessarily supported on all architectures, so add an option
+to allow the user to disable the PIE.
+
+This fixes the build on the m68k architecture:
