devel/orc: work around armv7 libc bug
The armv7 libc has a bug in printf() where printing a denormal double
may cause NUL bytes to be written out. This port tries to write a
diagnostic comment containing such a denormal to a C source file. The
bug causes the source file to be malformed, breaking the port and its
consumers.
Work around the bug by killing the offending part of the diagnostic
comment.
