kbuild: fix building sha256

2022-04-21T11:37:10+00:00

Pass down the correct EXTRA_CFLAGS to the compiler driver when building
assembler source.
Otherwise building busybox for a multilib other than the default failed
to link since hash_md5_sha256_x86-64_shaNI.o and
hash_md5_sha_x86-64_shaNI.o were built for the default arch which might
not what we requested in the EXTRA_CFLAGS.

build system: use SOURCE_DATE_EPOCH for timestamp if available

2021-06-05T16:13:00+00:00

The SOURCE_DATE_EPOCH is an effort of the Reproducible Builds
organization to make timestamps/build dates in compiled tools
deterministic over several repetitive builds.

Busybox shows by default the build date timestamp which changes whenever
compiled. To have a reasonable accurate build date while staying
reproducible, it's possible to use the *date of last source
modification* rather than the current time and date.

Further information on SOURCE_DATE_EPOCH are available online [1].

This patch modifies `confdata.c` so that the content of the
SOURCE_DATE_EPOCH env variable is used as timestamp.

To be independent of different timezones between builds, whenever
SOURCE_DATE_EPOCH is defined the GMT time is used.

gen_build_files: Use C locale when calling sed on globbed files

2021-06-05T15:36:19+00:00

When include/applets.h is re-generated

it generates code macros in include/applets.h e.g.

IF_XZCAT(APPLET_ODDNAME(xzcat, unxz, BB_DIR_USR_BIN, BB_SUID_DROP, xzcat))
...
IF_CHVT(APPLET_NOEXEC(chvt, chvt, BB_DIR_USR_BIN, BB_SUID_DROP, chvt))
...

sed is used to process source files like below to feed into this header
generation

sed -n 's@^//applet:@@p' "$srctree"/*/*.c "$srctree"/*/*/*.c

this means we let shell decide the order of .c files being fed into sed
tool, applets.h has code snippets thats generated out of code fragments
from these .c files and the order of the generated code depends on the
order of .c files being fed to sed and then piped to generate tool, even
though the generated code is logically same, it does result in re-odered
code in applets.h based on which shell was used during build on exact busybox
sources since sort order is different based on chosen locale and also default shell
being bash or dash

This sets the environment variable LC_ALL to the value C, which will
enforce bytewise sorting, irrespective of the shell
