BR2_BINFMT_FLAT configurations require the use of elf2flt. However, PHP uses -export-dynamic which breaks badly with elf2flt. Even a simple program fails to build: $ ./output/host/bin/arm-linux-gcc -Wl,-export-dynamic -o toto toto.c /home/thomas/projets/buildroot/output/host/opt/ext-toolchain/arm-buildroot-uclinux-uclibcgnueabi/bin/ld.real: section .junk LMA [0000000000000000,0000000000000027] overlaps section .text LMA [0000000000000000,0000000000006d07] -export-dynamic is clearly not useful for FLAT configurations, which are always statically linked, but it's quite a bit of work to change the PHP build system to use it only conditionall. It looks more like an interaction bug between gcc (which wants to put the .text section at address 0x0 in its linker script) and elf2flt, which wants to put its .junk section (containing the .rel.text stuff) also at address 0x0.
