Since 2.11.0, git does not default to 7 characters for short commit IDs,
instead automatically estimating the number of characters based on
repository size [1]. If the toolchain was compiled on a computer with
new version of git installed, commit ID will contain 8 characters, and
the check for the toolchain version will fail. As a workaround, trim the
commit ID to 7 characters when checking the version.

Fix warnings where undefined vars are used.
Make Kconfig emit "FOO=" for unset bool options
To ensure make variables are always defined, even if empty.
When writing auto.conf, include symbols disabled by dependency to make sure all make variables are always defined.

Cherry-picked from https://github.com/espressif/esp-idf/pull/138
Too hard to stage the dependencies so that all clean steps complete before any build steps begin. Also, using and then
deleting and then regenerating SDKCONFIG_MAKEFILE in one pass is really hard to manage successfully.
For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1"
Also refactored some of the generation of linker paths, library list. This required cleaning up the way the bootloader
project works, it's now mostly independent from the parent.
Each COMPONENT_DIRS directory can now either be a component directory, or a parent directory containing component
subdirectories.
When searching for components, skip any directory which doesn't have component.mk, Kconfig.projbuild, or
Makefile.projbuild in it. This helps with debugging, list-components output, etc.
Add new "make size_components" and "make size_files" targets for analysing makeup of the ELF file.
Plain "make size" output now looks like this:
Total sizes:
DRAM .data size: 11156 bytes
DRAM .bss size: 22304 bytes
Used static DRAM: 33460 bytes ( 294220 available, 10.2% used)
Used static IRAM: 80480 bytes ( 50592 available, 61.4% used)
Flash code: 421463 bytes
Flash rodata: 103824 bytes
Total image size:~ 616923 bytes (.bin may be padded larger)
Triggered on make 3.81, happens sometimes on Linux and always(?) on macOS. May depend on the order the OS' filesystem
resolves wildcards in.
Includes a revert to the LWIP component to verify this is properly fixed.

For example,
SRCDIRS = comp_a happy/comp_b /c/dev/comp_c
Then the following are built:
build/comp_a/libcomp_a.a
build/comp_b/libcomp_b.a
build/comp_c/libcomp_c.a
But when LD is run the -L is calculated as follows
-L build/comp_a
-L build/happy/comp_b
-L build//c/dev/comp_c
This means comp_b and comp_c are not found by LD. With this change set -L is calculated correctly for comp_b and comp_c
