Description Reindl Harald 2017-08-15 11:58:40 UTC 
httpd does exactly the same as apr-util (https://bz.apache.org/bugzilla/show_bug.cgi?id=61417)

configure: Configuring Apache Portable Runtime library...
configure: 
checking for APR... yes
 setting CPP to "gcc -m64 -O2 -g0 -mfpmath=sse -mavx -msse2avx -march=sandybridge -mtune=sandybridge -fopenmp -pipe -fno-strict-aliasing -fomit-frame-pointer -fexceptions -fstack-protector-strong --param=ssp-buffer-size=6 -D_FORTIFY_SOURCE=2 -Wstack-protector -Wformat -Werror=format-security -march=native -mtune=native -O3 -fno-strict-aliasing -fno-gcse-after-reload -fno-inline-functions -fno-ipa-cp -fno-ipa-cp-clone -fno-peel-loops -fno-predictive-commoning -fno-tree-loop-distribute-patterns -fno-unswitch-loops -fPIC -flto -ffat-lto-objects -fuse-ld=gold -fuse-linker-plugin -E"
 setting CPPFLAGS to " -DLINUX -D_REENTRANT -D_GNU_SOURCE"
Comment 1 Reindl Harald 2017-10-29 14:02:22 UTC 
well, and finally you can't use LTO for apr/apr-util because httpd don't build with the inherited -fno-fat-lto-objects even when you use -fno-fat-lto-objects in the httpd build itself

CCFLAGS/LDFLAGS are *not* your business when supplied in the environment

Comment 2 Eric Covener 2017-10-29 14:40:47 UTC 
Working as designed. If you want more control, build httpd w/ an included apr as the manual already describes.  If you re-open, please try to avoid all of the hysterics and editorializing and report something more concrete.

> report something more concrete

what more concrete than setting CPP to "gcc -m64 -O2 -g0 -mfpmath=sse -mavx -msse2avx -march=sandybridge -mtune=sandybridge..." is plain wrong because you override explicit configuration in the spec file below

# optimized compiler flags
export CFLAGS="%{optflags} %{O3_flags} -flto -ffat-lto-objects -fuse-ld=gold -fuse-linker-plugin -Wa,--noexecstack"
export CXXFLAGS="$CFLAGS"
export CC="gcc $CFLAGS"
export SH_LDFLAGS="-Wl,--as-needed -Wl,-z,now -Wl,-z,relro -Wl,-z,noexecstack -Wl,-z,nodump %{optflags} %{O3_flags} -flto -ffat-lto-objects -fuse-ld=gold -fuse-linker-plugin -Wa,--noexecstack"
