Change Makefile to generate/extract symbols files at src/symbols during post-compilation (last step of project build) (only macOS)

[jnasselle]

Epic
#9913

Description

This issue aims to extract the symbols (strip) once the generation of the binaries is done, this task is done as long as the variable STRIP_SYMBOLS is true, the output directory of this is wazuh/src/symbols

The default extension for symbols bundle should be .dSYM

Execute this task, based on the result of this spike: #9910 (comment)

DoD

• Execute dsymutil against binaries that will be part of the agent as post generation task
• Strip debug information of those binaries if STRIP_SYMBOLS is true

[RamiroRD]

Currently updating the makefile to use a static pattern rule that automatically generates the .dSYM folders in symbols/ from a list of executables and shared libraries that need to be stripped.
The following commands should be able to find all executables and shared libraries on macOS (they are meant to be run on <repo root>/src:

find . -maxdepth 1 -type f -not -path "./external/*"  -exec /bin/sh -c "file {} | grep 'bit executable' > /dev/null" \; -print 
find . -type f -not -path "./external/*" -name  "*.dylib" -print 

The only executable excluded here would be the sysinfo test tool, which should be fine.

BUILD_AGENT=$(shell find . -maxdepth 1 -type f -not -path "./external/*"  -exec /bin/sh -c "file {} | grep 'bit executable' > /dev/null" \; -print)
BUILD_AGENT+=$(shell find . -type f -not -path "./external/*" -name  "*.dylib" -print)


SYMBOLS_AGENT=$(BUILD_AGENT:./%=symbols/%.dSYM)

all: $(SYMBOLS_AGENT)

# This will extract symbols and then strip the binaries
$(SYMBOLS_AGENT): symbols/%.dSYM:%
	@echo $(SYMBOLS_AGENT)
	@echo "$@ <- $?"
	dsymutil -o $@ $?
	strip $?


clean:
	rm -rvf symbols/*.dSYM
	rm $(BUILD_AGENT)

prep:
	cp backup/* .
