Similar to libtool, (llvm-)otool only exists with a version suffix
on some systems (Ubuntu), which makes it annoying to use/find. Avoid
this, by switching to objdump. Which is a drop-in replacement.
This is related to #21778, and the switchover to using vanilla LLVM for
macOS.

This is only needed when compiling on macOS. This means we can also
better scope the usage of `-headerpad_max_install_names`.
|
|
Note that this is completely unrelated to gnu usage of libtool.

a3a2bd9e8ad360a63cc8bdfc365d8bfd25ecc720 ci: Drop no longer needed package-specific flags (Hennadii Stepanov)
071eef1e974f128131afe6c6b5c68a430c64687a build: Propagate user-defined flags to host packages (Hennadii Stepanov)
Pull request description:
On master (4f8b1f8759301d2553183e14f72444a0f1d80725) `{CPP,C,CXX,LD}FLAGS` that are specified in the command line are not propagated to packages:
```
$ make --no-print-directory -C depends print-libevent_cxxflags CXXFLAGS=-some-fancy-flag
libevent_cxxflags=-pipe -O2
```
This PR:
- propagates `{CPP,C,CXX,LD}FLAGS` to host packages:
```
$ make --no-print-directory -C depends print-libevent_cxxflags CXXFLAGS=-some-fancy-flag
libevent_cxxflags= -some-fancy-flag
```
- does not propagate `{CPP,C,CXX,LD}FLAGS` to native packages:
```
$ make --no-print-directory -C depends print-native_b2_cxxflags CXXFLAGS=-some-fancy-flag
native_b2_cxxflags=
```
- actually addresses the https://github.com/bitcoin/bitcoin/pull/23551#issuecomment-973896518

Qt's mkspec references the objcopy tool.
|
|
|
|
|
|
|
|
For example, doing:
make CC=clang CXX=clang++
Should now propagate these settings down to depends packages
