Description

@Sentimentron

Using Bazel 8.1.1 (also broken under Bazel 7.6.1)

Build command is:

bazel build -c opt --config=android_arm64 test:all

Example output is:

 Compiling kai/ukernels/matmul/matmul_clamp_f32_qai8dxp_qsi4c32p/kai_matmul_clamp_f32_qai8dxp4x8_qsi4c32p4x8_8x4x32_neon_i8mm.c failed: (Exit 1): gcc failed: error executing CppCompile command (from target @@+_repo_rules+KleidiAI//kai/ukernels/matmul:i8mm_impl_asm) /usr/bin/gcc -U_FORTIFY_SOURCE -fstack-protector -Wall -Wunused-but-set-parameter -Wno-free-nonheap-object -fno-omit-frame-pointer -g0 -O2 '-D_FORTIFY_SOURCE=1' -DNDEBUG -ffunction-sections ...

Use --verbose_failures to see the command lines of failed build steps.

Host is Linux x64. Shouldn't be using GCC - should be using the Android NDK for this. Does anybody use this flow regularly?

bazel build -c opt --config=android_arm64 //... and bazel build -c opt --config=android_arm64 :all don't work either.
