RedHat 8.0 has gcc 3.2 and binutils 2.13.90.0.2. TLS works. Our
gcc emits slightly different assembly that's not understood by
our assembler. The assembler shipped with RH 8 also doesn't
understand the assembly emitted by our compiler:

static.s: Assembler messages:
static.s:2: Warning: rest of line ignored; first ignored character is `%'
static.s:5: Error: unrecognized symbol type "li"
static.s:5: Warning: rest of line ignored; first ignored character is `,'
static.s:6: Error: expected comma after name `' in .size directive
static.s:6: Warning: rest of line ignored; first ignored character is `%'
static.s:7: Warning: rest of line ignored; first ignored character is `%'
static.s:17: Error: bad register name `%li at NTPOFF(%eax)'
