[bug#40164] Fix for libgccjit

[Ludovic Courtès]

Hi,

(+Cc bug.)

Formbi <address@hidden> skribis:

In that case, could you (1) arrange to write the search path in a way
that reuses (package-native-search-paths gcc-9), and (2) add a comment
explaining why “lib/gcc” is needed (it looks unusual)?

Thanks in advance,
Ludo’.
