[Buildroot] [PATCH 1/2] package/fontconfig: fix compile issue if BR2_DEBUG_3 has been selected

[Thomas Devoogdt <thomas@devoogdt.com>]

src/fcobjshash.gperf:568:7: error: stray '#' in program
src/fcobjshash.gperf:1:18: error: expected '=', ',', ';', 'asm' or '__attribute__' before numeric constant
    1 | #define __STDC__ 1
      |                  ^

This issue has been raised upstream [1], and reported in buildroot [2].
Upstream has not yet defined a solution, so force it to -g2 for the time being.
