When the parameter platform=foo-bar is passed to the script built-product-archive the script picks as platform name 'foo'.

This is correct for platform names like ios-wk2 or mac-wk2 where the generic platform name is 'mac' or 'ios', but not for 'jsc-only'

This may causes issues later when calling the script webkit-build-directory to determine the build directory path.


Example of the issue (with the patch from bug 249604)

OK $ ./Tools/Scripts/webkit-build-directory --release --configuration --cross-target=rpi3-32bits-mesa --jsc-only
/home/clopez/webkit/webkit/WebKitBuild/JSCOnly/Release_rpi3-32bits-mesa


FAIL $ ./Tools/Scripts/webkit-build-directory --release --configuration --cross-target=rpi3-32bits-mesa --jsc
/home/clopez/webkit/webkit/WebKitBuild/Unknown/Release_rpi3-32bits-mesa

It prints 'Unknown' as port directory because 'jsc' is not a valid port name in webkitdirs.pm so passing --jsc here is like passing any random string

FAIL $ ./Tools/Scripts/webkit-build-directory --release --configuration --cross-target=rpi3-32bits-mesa --magicstring
/home/clopez/webkit/webkit/WebKitBuild/Unknown/Release_rpi3-32bits-mesa


The script webkit-build-directory doesn't complain when you pass an unknown command line switch, so passing '--jsc' is the same than passing '--magicstring' in this example.

The script build-webkit however complains, and if you pass '--jsc' instead of '--jsc-only' you get:
