fldigi: variant "native" fails on AppleSilicon

[vk1kcm (Carl Makin)]

The AppleSilicon compiler doesn't support -march=native, instead configure uses "nativeARM". Attached patch passes "--enable-optimizations=nativeARM" to configure if os.arch eq "arm", or "--enable-optimizations=native" if it doesn't.

[vk1kcm (Carl Makin)]

Ahh, the patch includes the fix for flarq version as well. (Ignore this, removed in the latest patch)

[jmroot (Joshua Root)]

Needs to check ${configure.build_arch}, not ${os.arch}.

[vk1kcm (Carl Makin)]

Ok, updated patch to use ${configure.build_arch} instead of ${os.arch}. Replaced old patch.

Another option, newer versions of clang do support -march=native:

% uname -a

% clang++ -march=native test.cc
clang: error: the clang compiler does not support '-march=native'

% clang++-mp-15  -march=native test.cc
<OK>

Whitespace in the patch should be spaces, not tabs, to match the rest of the Portfile and its modeline.

[vk1kcm (Carl Makin)]

Tabs replaced with spaces and just the native patch.
