[bug] Architecture flag not set correctly with QNX SDP 7.0

[craigsacco]

I was tackling an issue attempting to compile Boost 1.66.0 through QNX SDP 7.0 to target the x86_64 target. I discovered that the -V switch wasn't being inserted into the q++ command line when different architecture or address model settings are passed into B2.

A similar issue was raised last year (issue #339) but the solution is not satisfactory as simply passing the -V flag through the compileflags and linkflags properties will be ignored when creating static libraries.

I ended up retrofitting tools/qcc.jam with the following changes to make it work correctly.

NOTE: line numbers applying to the current version of the file, not the version in 1.66.0.

Below line 80:

toolset.flags qcc.compile OPTIONS <architecture>x86/<address-model>32 : -Vgcc_ntox86 ;
toolset.flags qcc.compile OPTIONS <architecture>x86/<address-model>64 : -Vgcc_ntox86_64 ;
toolset.flags qcc.compile OPTIONS <architecture>arm/<address-model>32 : -Vgcc_ntoarmv7le ;
toolset.flags qcc.compile OPTIONS <architecture>arm/<address-model>64 : -Vgcc_ntoaarch64le ;

Below line 173:

toolset.flags qcc.link OPTIONS <architecture>x86/<address-model>32 : -Vgcc_ntox86 ;
toolset.flags qcc.link OPTIONS <architecture>x86/<address-model>64 : -Vgcc_ntox86_64 ;
toolset.flags qcc.link OPTIONS <architecture>arm/<address-model>32 : -Vgcc_ntoarmv7le ;
toolset.flags qcc.link OPTIONS <architecture>arm/<address-model>64 : -Vgcc_ntoaarch64le ;

Below line 212:

toolset.flags qcc.archive OPTIONS <architecture>x86/<address-model>32 : -Vgcc_ntox86 ;
toolset.flags qcc.archive OPTIONS <architecture>x86/<address-model>64 : -Vgcc_ntox86_64 ;
toolset.flags qcc.archive OPTIONS <architecture>arm/<address-model>32 : -Vgcc_ntoarmv7le ;
toolset.flags qcc.archive OPTIONS <architecture>arm/<address-model>64 : -Vgcc_ntoaarch64le ;

Modified the line in the archive action (line 226):

From: "$(CONFIG_COMMAND)" -A "$(<)" "$(>)"
To: "$(CONFIG_COMMAND)" $(OPTIONS) -A "$(<)" "$(>)"

The last change is the most important as it was inadvertently calling the 32-bit version of ar to archive object files compiled through the 64-bit version of gcc.

At least for my try to get Boost 1.73 to compile for QNX 7 I had to add

toolset.flags qcc.compile++ OPTIONS x86/32 : -Vgcc_ntox86 ;
toolset.flags qcc.compile++ OPTIONS x86/64 : -Vgcc_ntox86_64 ;
toolset.flags qcc.compile++ OPTIONS arm/32 : -Vgcc_ntoarmv7le ;
toolset.flags qcc.compile++ OPTIONS arm/64 : -Vgcc_ntoaarch64le ;

As well to compile C and C++ code for the correct architecture.
And of course add the fix of #453
