Looks like `.debug_line` information isn't being emitted for static functions.

Without `static` (two functions, main and test_static):
---
 Line Number Statements:
  [0x00000029]  Extended opcode 2: set Address to 0x0
  [0x00000034]  Set File Name to entry 1 in the File Name Table
  [0x00000036]  Special opcode 6: advance Address by 0 to 0x0 and Line by 1 to
2
  [0x00000037]  Special opcode 119: advance Address by 8 to 0x8 and Line by 2
to 4
  [0x00000038]  Special opcode 160: advance Address by 11 to 0x13 and Line by 1
to 5
  [0x00000039]  Special opcode 34: advance Address by 2 to 0x15 and Line by 1

With `static` (same number of functions):
---
 Line Number Statements:
  [0x00000029]  Extended opcode 2: set Address to 0x0
  [0x00000034]  Set File Name to entry 1 in the File Name Table
  [0x00000036]  Special opcode 13: advance Address by 0 to 0x0 and Line by 8 to
9
  [0x00000037]  Special opcode 62: advance Address by 4 to 0x4 and Line by 1 to
10
  [0x00000038]  Special opcode 76: advance Address by 5 to 0x9 and Line by 1 to
11
  [0x00000039]  Advance PC by 2 to 0xb
  [0x0000003b]  Extended opcode 1: End of Sequence
