kbuild: do not quote string values in include/config/auto.conf
The previous commit fixed up all shell scripts to not include
include/config/auto.conf.
Now that include/config/auto.conf is only included by Makefiles,
we can change it into a more Make-friendly form.
Previously, Kconfig output string values enclosed with double-quotes
(both in the .config and include/config/auto.conf):
CONFIG_X="foo bar"
Unlike shell, Make handles double-quotes (and single-quotes as well)
verbatim. We must rip them off when used.
There are some patterns:
[1] $(patsubst "%",%,$(CONFIG_X))
[2] $(CONFIG_X:"%"=%)
[3] $(subst ",,$(CONFIG_X))
[4] $(shell echo $(CONFIG_X))
These are not only ugly, but also fragile.
[1] and [2] do not work if the value contains spaces, like
CONFIG_X=" foo bar "
[3] does not work correctly if the value contains double-quotes like
CONFIG_X="foo\"bar"
[4] seems to work better, but has a cost of forking a process.
Anyway, quoted strings were always PITA for our Makefiles.
This commit changes Kconfig to stop quoting in include/config/auto.conf.
These are the string type symbols referenced in Makefiles or scripts:
ACPI_CUSTOM_DSDT_FILE
ARC_BUILTIN_DTB_NAME
ARC_TUNE_MCPU
BUILTIN_DTB_SOURCE
CC_IMPLICIT_FALLTHROUGH
CC_VERSION_TEXT
CFG80211_EXTRA_REGDB_KEYDIR
EXTRA_FIRMWARE
EXTRA_FIRMWARE_DIR
EXTRA_TARGETS
H8300_BUILTIN_DTB
INITRAMFS_SOURCE
LOCALVERSION
MODULE_SIG_HASH
MODULE_SIG_KEY
NDS32_BUILTIN_DTB
NIOS2_DTB_SOURCE
OPENRISC_BUILTIN_DTB
SOC_CANAAN_K210_DTB_SOURCE
SYSTEM_BLACKLIST_HASH_LIST
SYSTEM_REVOCATION_KEYS
SYSTEM_TRUSTED_KEYS
TARGET_CPU
UNUSED_KSYMS_WHITELIST
XILINX_MICROBLAZE0_FAMILY
XILINX_MICROBLAZE0_HW_VER
XTENSA_VARIANT_NAME
I checked them one by one, and fixed up the code where necessary.
