Yann E. MORIN 814f6e19e7 toolchain: allow PIC/PIE without RELRO
In commit 7484c1c3b8 (toolchain/toolchain-wrapper: add BR2_RELRO_),
we added the PIC/PIE flags, but based on the RELRO_FULL condition.

It is however totally possible to do a PIC/PIE executable without
RELRO_FULL, as it is also valid to do a PIC/PIE build with RELRO_PARTIAL.

Add a new option that now governs the PIC/PIE flags.

Note: it is unknown if RELRO_FULL really needs PIC/PIE or not, so we
keep the current situation, where RELRO-FULL forces PIC/PIE compilation.
Decoupling can come later from an interested party.

README

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.
