Giulio Benetti 4adc06b4f8 toolchain: introduce BR2_TOOLCHAIN_HAS_GCC_BUG_63261
dmalloc and fxload fail to build for the Microblaze architecture with
optimization enabled with gcc < 8.x, with the following failure:

  Error: PC relative branch to label logerror which is not in the instruction space
  Error: operation combines symbols in different segments

The following defconfig allows to reproduce the issue:

BR2_microblazeel=y
BR2_OPTIMIZE_2=y
BR2_KERNEL_HEADERS_5_0=y
BR2_GCC_VERSION_7_X=y
BR2_PACKAGE_FXLOAD=y

The gcc bug was reported at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63261 and is fixed as of
gcc 8.x.

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.
