+ post-process-pe: Fix format string warnings on 32-bit platforms
+
+ With -Werror these were causing build failures with stricter gcc:
+
+ .../post-process-pe.c: In function 'load_pe':
+ .../post-process-pe.c:177:55: error: format '%ld' expects argument of type 'long int', but argument 4 has type 'size_t' {aka 'unsigned int'} [-Werror=format=]
+ .../post-process-pe.c:192:56: error: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'UINT64' {aka 'long long unsigned int'} [-Werror=format=]
+ .../post-process-pe.c:236:31: error: format '%zu' expects argument of type 'size_t', but argument 2 has type 'UINT64' {aka 'long long unsigned int'} [-Werror=format=]
+ .../post-process-pe.c:39:32: note: in definition of macro 'debug'
+ .../post-process-pe.c:236:60: note: format string is defined here
+ .../post-process-pe.c:240:31: error: format '%zu' expects argument of type 'size_t', but argument 2 has type 'UINT64' {aka 'long long unsigned int'} [-Werror=format=]

+ tests: also look for system headers in multi-arch directories
+
+ On Debian(-derived) systems low-level system headers are under
+ /usr/include/<multi-arch path>, so look there too.
+
+ Otherwise we see stuff like:
+
+ gcc -O2 -fno-diagnostics-color -ggdb -std=gnu11 -isystem <foo>/shim.git/include/system -I<foo>/shim.git/gnu-efi/inc -I<foo>/shim.git/gnu-efi/inc/ia32 -I<foo>/shim.git/gnu-efi/inc/protocol -Iinclude -iquote . -isystem /usr/include -isystem /usr/lib/gcc/i686-linux-gnu/11/include -mno-mmx -mno-sse -mno-red-zone -nostdinc -maccumulate-outgoing-args -m32 -DMDE_CPU_IA32 -DPAGE_SIZE=4096 -fshort-wchar -fno-builtin -rdynamic -fno-inline -fno-eliminate-unused-debug-types -fno-eliminate-unused-debug-symbols -gpubnames -grecord-gcc-switches -Wall -Wextra -Wno-missing-field-initializers -Wsign-compare -Wno-deprecated-declarations -Wno-unused-but-set-variable -Wno-unused-variable -Wno-pointer-sign -Werror -Werror=nonnull -Werror=nonnull-compare -DEFI_FUNCTION_WRAPPER -DGNU_EFI_USE_MS_ABI -DPAGE_SIZE=4096 -DSHIM_UNIT_TEST -DDEFAULT_DEBUG_PRINT_STATE=0 -isystem include-fixed -o test-csv csv.c test-csv.c test.c libefi-test.a -lefivar
