1.85.0 Beta 1 RC 1 does not build on Mac OS X with gcc

[mclow]

Copied from the ML (thanks to Matt Borland for the report)

I have successfully built the libraries on M1 Mac running macOS Sonoma 14.3.1 with Clang 17.0.6 using cxxstd=11,14,17,20,23.

On the same platform using homebrew gcc-13 13.2.0 I get build failures with boost.fiber and boost.coroutine.

b2 has the following error:

That's actually a problem in Context, and the fix is fairly trivial. This section from build/Jamfile:

context/build/Jamfile.v2

Lines 210 to 231 in 77de3d5

	# ARM64/AAPCS/MACH-O
	alias asm_sources
	: asm/make_arm64_aapcs_macho_gas.S
	asm/jump_arm64_aapcs_macho_gas.S
	asm/ontop_arm64_aapcs_macho_gas.S
	: <abi>aapcs
	<address-model>64
	<architecture>arm
	<binary-format>mach-o
	<toolset>clang
	;
	alias asm_sources
	: asm/make_arm64_aapcs_macho_gas.S
	asm/jump_arm64_aapcs_macho_gas.S
	asm/ontop_arm64_aapcs_macho_gas.S
	: <abi>aapcs
	<address-model>64
	<architecture>arm
	<binary-format>mach-o
	<toolset>darwin
	;

is missing a <toolset>gcc alternative.

Or, another way to fix it is to just remove the <toolset> conditions from most places, including this one.

untested because I don't own a Mac OS running on AMR64
