Previous solution by using objcopy uses a quirky behaviour of the GNU
objcopy and there is no equivalent option in llvm-objcopy.
Instead of removing symbols, extract and repack libgcc to only include
required objects.

I'm not sure if these sections are used, but by adding them to
libgcc_stripped.a, we can end up with multiple .gnu_debuglink sections in
an executable, where the first two unhelpfully point at "libgcc.a". e.g.:
$ readelf -SW -x.gnu_debuglink out/target/product/walleye/system/bin/bootstrap/linker64
...
Section Headers:
...
[18] .gnu_debuglink PROGBITS 0000000000000000 10f19c 000020 00 0 0 1

We use libgcc as fallback for symbols not present in libclang_rt
builtins, however we didn't know what exact symbols were being used,
some may not be intended to fallback.
Create libgcc_stripped, which only contains unwind symbols from libgcc.

Added synopsis to the following modules under cc package:
* llndk_headers
* llndk_library
* vendor_public_library
* toolchain_library

Test: Generated the documentation and verified that the synopsis was
added to each of the module.

Bug: http://b/128524141
Include libprofile-extras (defined in system/extras/toolchain-extras) to
all modules that need a coverage variant. Also add
'-uinit_profile_extras' when linking with coverage. This causes the
setup code in libprofile-extras to be linked into binaries/libraries
with coverage enabled.
We add the static library to the non-coverage variants as well but is a
no-op for them (since the '-u...' flag is not added for them).
Adding this dependency creates several circular dependencies since
coverage variants were being created for other module types that never
had any compilation or linking done during the build. This change stops
creating coverage variants for toolchain_library, cc_prebuilt_library_*,
cc_library_headers module types (by adding a function to the linker
interface to specify whether native coverage is enabled).

Most everything in Soong is using clang (and we're getting very close
for Make as well), so remove the ability to select GCC to build a
module.
We still need to keep the internal functionality around to find libgcc.a
and other toolchain_library modules with GCC.

there's no use case for prepending/appending to bool, and string
properties within module struct. Declearing "*bool" and "*string" almost
cover everything user need.
I did see one case that user specify relative_install_path as
path prefix in cc_defaults, and concatenate with the one in real module
to get the final relative install path in Android.bp <bionic/tests/libs>.
