Improve Graal doc again
After double checking findings, document precisely which items are not
functional. The list now looks a lot better than before.
It is not possible to support more than a very specific Graal version at
this time, so specify 19.3 must be used [hopefully the minor 19.3.x
versions will not break anything ... but it's almost certain the next
major "stable" versions will need changes that will force dropping
support for 19.3].
Talk about --static since it is useful and works, mention the needed
static libraries (if one is missing, the linker of course starts
screaming in a very ugly way).
