This reverts commit 8e91385a2c.
This commit is incorrect, as it is perfectly valid for
BR2_TOOLCHAIN_EXTERNAL_PATH to be empty. The help text of
BR2_TOOLCHAIN_EXTERNAL_PATH even documents it as a supported case:
If empty, the compiler will be searched in $PATH.
Commit 392b0a26f5 ("toolchain-external:
default BR2_TOOLCHAIN_EXTERNAL_PATH to empty") even made that the
default saying "In addition, it in fact works correctly when it is
empty. In that case, the toolchain will be searched in PATH."
A user has reported that commit
8945ba4948 (the backport of 8e91385a2c to
the 2022.02.x LTS branch) breaks his use-case:

Convert BR2_TOOLCHAIN_EXTERNAL_PATH to an absolute path when used.
Otherwise the symbolic links to the external toolchain binaries are
not installed in host/bin when BR2_TOOLCHAIN_EXTERNAL_PATH is relative.
This happens because TOOLCHAIN_EXTERNAL_INSTALL_WRAPPER
changes directory into host/bin to create the symbolic links.
From there the tools are no longer found via the relative path and
a single symbolic link host/bin/$(prefix)-* is created instead.
Although relative paths sounds like something less than ideal to put in
a Buildroot configuration, it's actually rather typical to put the
buildroot sources as a submodule (or subdirectory) of custom sources
(either in a BR2_EXTERNAL or not), in which case the relative path is
well-defined.

represents the result of re-running the gen-bootlin-toolchains script.
The only part that isn't auto-generated are the contents of
Config.in.legacy, which account for the replacement of the RISC-V LP64
toolchain by RISC-V LP64D toolchains.

gcc installs a libstdcxx-...so-gdb.py file that gdb will load automatically
when it loads libstdcxx.so, via the mechanism described at [1].
However, the auto-load file installed by gcc contains hardcoded paths
referring to the location where the (external) toolchain was built, which
are normally not available.
Fix up the paths in the load file so that the pretty printers can be loaded
automatically.
Note that gdb will only auto-load the file if its location is marked as
'safe'. A subsequent commit will take care of that.
Technically, there could be more than one load file, e.g. in lib and
usr/lib, so fix them all. This was for example observed in
BR2_TOOLCHAIN_EXTERNAL_ARM_AARCH64.
In a very specific case with a local custom toolchain, there were actually
two 'python' directories, which would break the sed command, so arbitrarily
limit to the first one encountered.

While testing Buildroot on a Cortex-A5 that doesn't provide NEON, we
found out that a system generated with the ARM toolchain from Arm
didn't boot. It turns out that this ARM toolchain is built with:
--with-arch=armv7-a --with-fpu=neon --with-float=hard --with-mode=thumb
So, it uses NEON as its FPU, which means it can only work on CPU cores
that have NEON support. This commit adds the appropriate dependency to
the toolchain-external-arm-arm package, and adjusts the Config.in help
text accordingly.
While at it, it also drops the part of the Config.in help text that
says the code is tuned for Cortex-A9, as it is not the case: it was
the case for the Linaro toolchain (built with --with-tune=cortex-a9),
but not for the ARM toolchain, for which no specific --with-tune is
passed.

The external toolchain configure step calls the
check_kernel_headers_version make function to compare the kernel
headers version declared in the configuration with the actual kernel
headers of the toolchain.
This function takes 4 arguments, but due to a missing comma what
should be the first two arguments are both passed into the first
argument. Due to this, when check_kernel_headers_version does:
if ! support/scripts/check-kernel-headers.sh $(1) $(2) $(3) \
$(if $(BR2_TOOLCHAIN_HEADERS_LATEST),$(4),strict); \
Then:
$(1) contains "$(BUILD_DIR) $$(call toolchain_find_sysroot,$$(TOOLCHAIN_EXTERNAL_CC))"
$(2) contains "$$(call qstrip,$$(BR2_TOOLCHAIN_HEADERS_AT_LEAST))"
$(3) contains "$$(if $$(BR2_TOOLCHAIN_EXTERNAL_CUSTOM),loose,strict))"
So from the point of view of check-kernel-headers.sh, it already has
four arguments, and therefore the additional argument passed by:
$(if $(BR2_TOOLCHAIN_HEADERS_LATEST),$(4),strict); \
is ignored, defeating the $(BR2_TOOLCHAIN_HEADERS_LATEST) test.
The practical consequence is that a toolchain that has 5.4 kernel
headers but declared as using 5.3 kernel headers does not abort the
build, because the check is considered "loose" while it should be
"strict".
