Disable rwx segment linker error

An update on the linker will now refuse to create binaries with a
loadable memory segment that has read, write and execute permissions
set.
mesa creates one unless "glx-read-only-text" is enabled, however, the
documentation for "glx-read-only-text" reads:

  "Disable writable .text section on x86 (decreases performance)"

In order to avoid possible performance regressions, disable the linker
error.
