Actually it sounds like the two problems might be related.  It would
appear that you are having problems with the linker script that you
are using.   This script appears to be incompatible with the
profiling library.  ie it appears that the profiling library is
expecting the linker script to define a symbol called __text_start and
also allocate enough space for the program headers.

You have already found out how to allocate more space for the
headers.  Defining the __text_start symbol should be relatively easy
too.  Take a look at the file ld/scripttempl/hppaelf.sc where it has
these lines:

  .text 0x1000 ${RELOCATING++${TEXT_START_ADDR}}:
  {
    ${RELOCATING+__text_start = .};

Cheers
