m68k does not seem to really support PIE as it raises the following
build failure with aer-inject:
/usr/lfs/hdd_v1/rc-buildroot-test/scripts/instance-1/output/host/opt/ext-toolchain/bin/../lib/gcc/m68k-buildroot-linux-uclibc/7.4.0/../../../../m68k-buildroot-linux-uclibc/bin/ld: /usr/lfs/hdd_v1/rc-buildroot-test/scripts/instance-1/output/host/m68k-buildroot-linux-uclibc/sysroot/usr/lib/Scrt1.o: in function `lib_main':
(.text+0x4): undefined reference to `__shared_flat_add_library'
/usr/lfs/hdd_v1/rc-buildroot-test/scripts/instance-1/output/host/opt/ext-toolchain/bin/../lib/gcc/m68k-buildroot-linux-uclibc/7.4.0/../../../../m68k-buildroot-linux-uclibc/bin/ld: final link failed: bad value
We also have another build failure with uclibc on microblazeel:
/home/buildroot/autobuild/instance-1/output-1/host/lib/gcc/microblazeel-buildroot-linux-uclibc/8.3.0/../../../../microblazeel-buildroot-linux-uclibc/bin/ld: final link failed: bad value
collect2: error: ld returned 1 exit status
Makefile.in:114: recipe for target '../utils/getconf' failed
So add a BR2_TOOLCHAIN_SUPPORTS_PIE dependency on BR2_PIC_PIE

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
