A PT_PHDR corruption was previously reported and fixed in [1]: the issue was
that the VirtAddr field of the PT_PHDR program header would get overwritten
with the file offset of the program header table rather than the virtual
address. A testcase for this was also added in [2]. However, the tescase is not
included in the Makefile.am regression testsuite and also tries to run a x86_64
prebuilt binary unconditionally, which would not work on other architectures.
To fix this, create a standalone testcase for the PT_PHDR VirtAddr field
corruption and include it in Makefile.am. In order to reproduce [1], a binary
with the following characteristics is needed:
- the ELF file type must be ET_DYN
- the ELF file must contain a PT_PHDR program header
- the file offset and the VirtAddr field of the PT_PHDR program header must be
different
