Tools used within the sandbox are now copied into the sandbox, see aosp/1531944. This caused the modified headers_install.sh, which is no longer installed, to point to a non-existent location. This change adds a level of indirection. The gen-headers_install.sh module no longer uses unifdef as a tool, but still modifies the headers_install.sh script, but not to point to a particular location, but to find the unifdef tool via an environment variable, LOC_UNIFDEF. Next, we modify qti_generate_kernel_headers_arm and qti_generate_kernel_headers_arm64 to need the unifdef tool (which is copied into the sandbox for these tools). We add a new --unifdef option to the kernel_headers.py script so that it can find the tool in the sandbox. The kernel_headers.py script sets the LOC_UNIFDEF environment variable before invoking the altered headers_install.sh script (also copied into the sandbox). Finally, we generate gen_headers_arm.bp and gen_headers_arm64.bp with all of these changes.
