If have searched for GLIBCPIE within all meta-files, but it seems that GLIBCPIE
is already empty.
varga-r@ubuntu:~/projects/yocto-tq-mba6x$ grep -rnI "GLIBCPIE"
poky/meta/conf/distro/include/security_flags.inc:9:# If static PIE is known to
work well, GLIBCPIE="--enable-static-pie" can be set
poky/meta/conf/distro/include/security_flags.inc:34:GLIBCPIE_powerpc = ""
poky/meta/recipes-core/glibc/glibc_2.29.bb:73:GLIBCPIE ??= ""
poky/meta/recipes-core/glibc/glibc_2.29.bb:89: ${GLIBCPIE} \
Then I searched for "pie" within the generated glibc sources... and found many
search results including " *-pie* " or " *-fpie* " as passed compiler parameter
for various files (note that I pasted two lines only!):

I am not sure, if this is relevant... just in case.
Thanks for your support.
