When BR2_TOOLCHAIN_HAS_LIBQUADMATH is set, --enable-libquadmath-support
option is missing. So the float128 support is not fully enabled in gcc.
This lead to a build issue with gcc 12 on PowerPC power8 due to missing
M_2_SQRTPIq definition (provided by libquadmath.h).
../../../libgfortran/intrinsics/erfc_scaled.c: In function ‘erfc_scaled_r17’:
../../../libgfortran/intrinsics/erfc_scaled.c:143:22: error: ‘M_2_SQRTPIq’ undeclared (first use in this function); did you mean ‘M_2_SQRTPIf’?
143 | # define _M_2_SQRTPI M_2_SQRTPIq
| ^~~~~~~~~~~
This is fixed by adding --enable-libquadmath-support (like crosstool-ng
handling [1]).

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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
