dev-libs/libgcrypt-1.11.0-r1 fails to build on POWER8 with USE flag asm enabled:

/bin/sh ../libtool  --tag=CC   --mode=link powerpc64le-unknown-linux-gnu-gcc  -mcpu=power8 -O2 -pipe -fvisibility=hidden -fno-delete-null-pointer-checks -Wall  -Wl,-O1 -Wl,--as-needed -Wl,--undefined-version -o mpicalc mpicalc-mpicalc.o libgcrypt.la -lgpg-error

collect2: error: ld returned 1 exit status

With USE=-asm the issue does not occur.

The issue affects all 1.11.0 ebuilds (including previous stable 1.11.0 and latest 1.11.0-r2).

All libgcrypt-1.10.3 ebuild compile fine with both USE=asm and USE=-asm.

Reproducible: Always

Steps to Reproduce:
1. emerge libgcrypt with USE=asm
