parisc uses ^ in some identifiers. Therefore we need something like [A-Za-z0-9_$^]* in linker script. This wasn't working with GNU ld - ^ is not a valid char for pattern. Use of more general [!.]* was also impossible - ! is not a valid char too.
Therefore I asked binutils people to fix this (they agreed) and decided to wait for a fixed binutils to be released.
