Hi Simon,

It seems the buildman option toolchain-wrapper is no more working since v2022.07-rc2

=> with the lines in ${HOME]/.buildman :

[toolchain-wrapper]     wrapper: ccache

I have compilation error for some ARM target with EFI support, for example for stm32mp15_defconfig.

Tests in include/efi_default_filename.h are introduced with commit 4e65ca00f3a3 ("efi_loader: bootmgr: add booting from removable media")

for examples:

#if HOST_ARCH == HOST_ARCH_X86

but ${HOST_ARCH} is empty.

The issue occurs because when CROSSCOMPILER="ccache arm-linux-gnueabi-"

in Makefile, MK_ARCH have invalid value and thus HOST_ARCH is empty...

The issue can be avoid with the dirty patch:

----------------------------------- Makefile ----------------------------------- index d394340221..3999bbcd71 100644 @@ -21,7 +21,7 @@ include include/host_arch.h  ifeq ("", "$(CROSS_COMPILE)")    MK_ARCH="${shell uname -m}"  else -  MK_ARCH="${shell echo $(CROSS_COMPILE) | sed -n 's/^[[:space:]]*([^/]*/)*([^-]*)-[^[:space:]]*/\2/p'}" +  MK_ARCH="${shell echo $(CROSS_COMPILE) | sed -n 's/ccache//;s/^[[:space:]]*([^/]*/)*([^-]*)-[^[:space:]]*/\2/p'}"  endif

But I solve only the issue only for "ccache" wrapper !

Do you think we need to remove this option in "toolchain-wrapper" buildman ?
