Build: allow EXTRA_CFLAGS, e.g., -fPIE (needed by EL8/GCC 8.5) #1752

Closed space88man closed 8 months ago

space88man commented 8 months ago

EL8/GCC 8.5 needs -fPIE on building daemon/ on master, mr12.0.1. This PR allows make to receive distro-specific flags.

# build with distro specific flags
EXTRA_CFLAGS=-fPIE make

Reason for this PR: error on EL8 on current master without -fPIE:

/usr/bin/ld: dynamic STT_GNU_IFUNC symbol `s16_mix_in.lto_priv.206' with pointer equality in `/tmp/cceywfR9.ltrans1.ltrans.o' can not be used when making an executable; recompile with -fPIE and relink with -pie
collect2: error: ld returned 1 exit status

On EL8 this error is specific to the system GCC 8.5; -fPIE is not needed with gcc-toolset-[9-12].

User can already override CFLAGS=xxxxxxxxxxxxxx make at the start of invocation.
